Trilon M Liquid

Trilon M liquid (Trilon M sv, TRILON M LIQUID) T is an aqueous solution of the trisodium salt of methylglycinediacetic acid (Na3MGDA). It finds application in detergents, cleaning, textiles, soap, metal plating, oil and gas, and water-softening products. Trilon M liquid (Trilon M sv, TRILON M LIQUID) is readily biodegradable.

Trilon M liquid (Trilon M sv, TRILON M LIQUID), methylglycinediacetic acid trisodium salt (MGDA-Na3) or trisodium α-DL-alanine diacetate (α-ADA), is the trisodium anion of N-(1-carboxyethyl)iminodiacetic acid and a tetradentate complexing agent. It forms stable 1:1 chelate complexes with cations having a charge number of at least +2, e.g. the “hard water forming” cations Ca2+ or Mg2+. α-ADA is distinguished from the isomeric β-alaninediacetic acid by better biodegradability and therefore improved environmental compatibility.

Production of Trilon M liquid (Trilon M sv, TRILON M LIQUID)

The patent literature on the industrial synthesis of Trilon M liquid (Trilon M sv, TRILON M LIQUID) describes the approaches for solving the key requirements of a manufacturing process that can be implemented on an industrial scale, characterized by

Achieving the highest possible space-time yields

Simple reaction control at relatively low pressures and temperatures

Realization of continuous process options

Achieving the lowest possible levels of impurities, particularly nitrilotriacetic acid, which is suspected of being carcinogenic

Use of inexpensive raw materials, e.g. instead of pure L-alanine the raw mixture of Strecker synthesis from methanal, hydrogen cyanide and ammonia

Avoidance of complex and yield-reducing isolation steps; instead, direct further use of the crude reaction solutions or precipitates in the following process step.

An obvious synthesis route to α-alaninediacetic acid is from racemic α-DL-alanine, which provides racemic α-ADA by double cyanomethylation with methanal and hydrogen cyanide, hydrolysis of the intermediately formed diacetonitrile to the trisodium salt and subsequent acidification with mineral acids in a 97.4% overall yield.[4] In a later patent specification, however, only an overall yield of 77% and an NTA content of 0.1% is achieved with practically the same quantities of substances and under practically identical reaction conditions.

MGDA Alanin

This later patent specification also indicates a process route via alaninonitrile, which is obtained by Strecker synthesis from hydrogen cyanide, ammonia and methanal and converted to methylglycinonitrile-N,N-diacetonitrile by double cyanomethylation (step 1). The three nitrile groups are then hydrolyzed with sodium hydroxide to α-ADA (step 2). The total yield is given as 72%, the NTA content as 0.07%.

MGDA Alaninonitril

One variant of the reaction involves iminodiacetonitrile or iminodiacetic acid (step 1′), which reacts in a weakly acidic medium (pH 6) with hydrogen cyanide and ethanal to form methylglycinonitrile-N,N-diacetic acid, the nitrile group of which is hydrolyzed with sodium hydroxide to Trilon M liquid (Trilon M sv, TRILON M LIQUID) (step 2′). The reactant iminodiacetic acid is accessible at low cost by dehydrogenation of diethanolamine. Again, the total yield is given as 72%, the NTA content as 0.07%.

A further variant is suitable for continuous production, in which ammonia, methanal and hydrogen cyanide react at pH 6 to form iminodiacetonitrile, which in a strongly acidic medium (pH 1.5) reacts with ethanal to produce trinitrile methylglycinonitrile-N,N-diacetonitrile in a very good yield of 92%. (step 1).

MGDA Iminodiacetonitril

Alkaline hydrolysis (step 2) results in a total yield of 85% Trilon M liquid (Trilon M sv, TRILON M LIQUID) with an NTA content of 0.08%. This process variant seems to fulfil the above-mentioned criteria best.

A low by-product synthesis route for Trilon M liquid (Trilon M sv, TRILON M LIQUID) has recently been described, in which alanine is ethoxylated with ethylene oxide in an autoclave to form bis-hydroxyethylaminoalanine and then oxidized to α-ADA at 190 °C with Raney copper under pressure.[6]

MGDA Ethoxylierung

The yields are over 90% d.Th., the NTA contents below 1%. The process conditions make this variant rather less attractive.

Properties of Trilon M liquid (Trilon M sv, TRILON M LIQUID)

The commercially available Trilon M liquid (Trilon M sv, TRILON M LIQUID) (84% by weight) is a colourless, water-soluble solid whose aqueous solutions are rapidly and completely degraded even by non-adapted bacteria. Aquatic toxicity to fish, daphnia and algae is low.[7] Trilon M liquid (Trilon M sv, TRILON M LIQUID) is described as readily biodegradable (OECD 301C) and is eliminated to >90 % in wastewater treatment plants.[8] Trilon M liquid (Trilon M sv, TRILON M LIQUID) has not yet been detected in the discharge of municipal and industrial sewage treatment plants. In addition to their very good biodegradability, Trilon M liquid (Trilon M sv, TRILON M LIQUID) solutions are characterized by high chemical stability even at temperatures above 200 °C (under pressure) in a wide pH range between 2 and 14 as well as high complex stability compared to other complexing agents of the aminopolycarboxylate type.

The complex formation constants of the biodegradable chelators α-ADA and IDS are in a range suitable for industrial use, but clearly below those of the previous standard EDTA.

In solid preparations, Trilon M liquid (Trilon M sv, TRILON M LIQUID) is stable against oxidizing agents such as perborates and percarbonates, but not against oxidizing acids or sodium hypochlorite.

Use of Trilon M liquid (Trilon M sv, TRILON M LIQUID)

Like other complexing agents in the aminopolycarboxylic acid class, Trilon M liquid (Trilon M sv, TRILON M LIQUID) (α-ADA) finds due to its ability to form stable chelate complexes with polyvalent ions (in particular the water hardening agents Ca2+ and Mg2+, as well as transition and heavy metal ions such as Fe3+, Mn2+, Cu2+, etc.) use in water softening, in detergents and cleaning agents, in electroplating, cosmetics, paper and textile production. Due to its stability at high temperatures and pH values, α-ADA should be particularly suitable as a substitute for the phosphates banned in the EU from 2017, such as sodium tripolyphosphate (STPP)[12] in tabs for dishwashers.

BASF SE is the most important manufacturer of α-ADA under the brand name Trilon M liquid (Trilon M sv, TRILON M LIQUID), has large-scale plants in Ludwigshafen and Lima, Ohio, and is currently expanding its existing capacities with another large-scale plant at Evonik’s site in Theodore, Alabama.

Description of Trilon M liquid (Trilon M sv, TRILON M LIQUID)

Trilon M liquid (Trilon M sv, TRILON M LIQUID) is a chelating agent that delivers a non-toxic, environmentally friendly alternative to phosphates and other strong chelates. Methylglycinediacetic acid (MGDA) is the active ingredient and exceeds alternative products, like citrates, at removing lime scale and tough stains. Efficiently dissolve inorganic deposits and scales that produce undesirable effects like striking and spotting in dish wash and hard surface applications or limit the performance of surfactants and other additives in cleaners and detergents.

Trilon M liquid (Trilon M sv, TRILON M LIQUID) chelating agent improves cleaning performance in hard surface, automatic dishwasher and laundry operations. I&l customers can use lower concentrations, due to its low molecular weight, of this strong complexing agent in their cleaning formulations, making it more cost effective. This product is effective in both alkaline and acidic cleaners, and also demonstrates effective cleaning ability in a variety of applications, including general purpose cleaners, floor care products, warewashing detergents, disinfectants and sanitizers, laundry detergents, automatic dishwashers, vehicle wash aids, and hand cleansers.

Trilon M liquid (Trilon M sv, TRILON M LIQUID) is extremely efficient in combating hard water and allowing for the best cleaning performance to shine through. In formulas with anionic surfactants, it is especially important to have an effective chelating agent like Trilon M liquid (Trilon M sv, TRILON M LIQUID), particularly in hard water conditions. Other chelating agents just don’t perform as well, and without the addition of one at all, there is hardly any cleaning shown.

The Trilon M liquid (Trilon M sv, TRILON M LIQUID) are very effective complexing agents for calcium in the alkaline pH range. This is an advantage in many detergent and cleaner applications.

➔ The Trilon M liquid (Trilon M sv, TRILON M LIQUID) are less likely to crystallise in the acidic pH

range than other aminocarboxylic acids, and they are still capable

of complexing iron ions effectively in the pH 2 – 3 range.

Comparison with weak complexing agents:

Weak complexing agents are incapable of reducing the concentration of free metal ions in aqueous systems to the same extent as the Trilon M liquid (Trilon M sv, TRILON M LIQUID),

and the result is that they are unable to prevent metal ions from playing a

disruptive role in chemical processes.

The Trilon M liquid (Trilon M sv, TRILON M LIQUID) are chemically very stable.

The Trilon M liquid (Trilon M sv, TRILON M LIQUID) have been shown to be very stable compared to other organic complexing agents such as citric acid, tartaric acid and gluconates,

especially at high temperatures.

Whereas inorganic sequestring agents (eg. phosphates) may hydrolyse at high temperatures, Trilon M liquid (Trilon M sv, TRILON M LIQUID) are stable – even when heated to 200 °C under pressure. Trilon M Powder and Trilon M Granules begin to decompose at approx. 300 °C.

The Trilon M liquid (Trilon M sv, TRILON M LIQUID) are resistant to strong acids and strong bases. They are gradually broken down by chromic acid, potassium permanganate and other strong oxidizing agents. Stability in the presence of hydrogen peroxide, percarbonate and perborate is sufficient for joint application. Nevertheless, we do not recommend combining Trilon M liquid (Trilon M sv, TRILON M LIQUID) and peroxides in liquid formulations.

Sodium hypochlorite and other substances that release chlorine cause the Trilon M liquid (Trilon M sv, TRILON M LIQUID) to decompose. Alkaline earth and heavy metal complexes are broken down.

➔ Formulations that contain complexing agents have to remain chemically unchanged in storage and during transport in order to be able to unfold their full action. Many readily biodegradable complexing agents such as iminodisuccinates (IDS) and citrates are not sufficiently stable. The Trilon M liquid (Trilon M sv, TRILON M LIQUID) have excellent chemical stability under a wide range of conditions, and this ensures that formulations that contain Trilon M liquid (Trilon M sv, TRILON M LIQUID) remain effective over long periods. pH stability The Trilon M liquid (Trilon M sv, TRILON M LIQUID) are resistant to being broken down across the whole pH 2 – 14 range, even at elevated temperatures. For instance, formulations that contain Trilon M liquid (Trilon M sv, TRILON M LIQUID) and high concentrations of sodium hydroxide remain stable and do not precipitate. Other readily biodegradable complexing agents such as iminodisuccinate precipitate in alkaline media, and these weak complexing agents are then no longer able to keep metal ions in solution.

The miscibility and stability of the Trilon M liquid (Trilon M sv, TRILON M LIQUID) are excellent, even in highly acidic solutions. Many complexing agents cannot be employed in acidic formulations because they precipitate in the form of their sparingly soluble free acids. The Trilon M liquid (Trilon M sv, TRILON M LIQUID) have the advantage that they remain soluble and chemically stable, even in the acidic pH range.

➔ The Trilon M liquid (Trilon M sv, TRILON M LIQUID) boost the performance of highly alkaline formulations.

➔ The Trilon M liquid (Trilon M sv, TRILON M LIQUID) can also be employed in acidic formulations.

➔ The Trilon M liquid (Trilon M sv, TRILON M LIQUID) do not decompose even at an extreme pH.

Corrosion The Trilon M liquid (Trilon M sv, TRILON M LIQUID) stabilize polyvalent metal ions, which means that they can increase the rate at which metals dissolve. Nevertheless, with the exception of aluminium, an oxidizing agent such as air always has to be present for corrosion to take place. Unalloyed steel is prone to corrosion in media that contain air, but corrosion can be reduced substantially if the pH is in the alkaline range and can be eliminated almost completely if oxygen and other oxidizing agents are excluded. Steel cleaned with the Trilon M liquid (Trilon M sv, TRILON M LIQUID) in the slightly alkaline range, which is the optimum pH range for the Trilon M liquid (Trilon M sv, TRILON M LIQUID), is much less prone to corrosion than if it is cleaned with acids.

The only type of corrosion that has been observed with the Trilon M liquid (Trilon M sv, TRILON M LIQUID) is uniform corrosion: pitting or stress cracking have not been observed in

media with a low chloride content. One of the advantages of the Trilon M liquid (Trilon M sv, TRILON M LIQUID) is that they can be supplied with a very low chloride content (< 20 mg/kg). The following information on materials is of a very general nature, because corrosion depends on many different factors such as exposure to air, galvanic corrosion caused by the presence of different metals and by the flow patterns of liquids. The compatibility of Trilon M liquid (Trilon M sv, TRILON M LIQUID) with different materials needs to be tested in each individual case.

Austenitic stainless steels such as AISI/SAE 304, 316 Ti and 321 are very effective for vessels used to store and transport Trilon M liquid (Trilon M sv, TRILON M LIQUID). The corrosion resistance of ferritic carbon steel such as ASTM A201 Grade B (European Material No. P265GH) is limited. A rate of corrosion of 0.01 mm/a has been measured at 50 °C and air exclusion. Crevice corrosion has also occasionally been observed on welded joints, and so we would not recommend storing the Trilon M liquid (Trilon M sv, TRILON M LIQUID) in vessels made from unalloyed carbon steel for any prolonged length of time. The rate of corrosion can be reduced by

removing the air from the system.

Aluminium and aluminium alloys such as AL 7075 T6 (European Material No. 3.4365) are not resistant to Trilon M liquid (Trilon M sv, TRILON M LIQUID), because Trilon M liquid (Trilon M sv, TRILON M LIQUID) is alkaline and aluminium is quickly corroded by strong bases. Solutions that contain Trilon M liquid (Trilon M sv, TRILON M LIQUID) are much less corrosive to aluminium if their pH is adjusted to 5 – 7. The following points need to be taken into account when comparing the performance of the Trilon M liquid (Trilon M sv, TRILON M LIQUID) with weaker complexing agents.

➔ The quantity of complexing agent that is required to sequester a given concentration of calcium ions depends on the strength of the complexing agent. The Trilon M liquid (Trilon M sv, TRILON M LIQUID) have a more effective complexing action, and much smaller quantities are required to obtain the same effect as with IDS.

➔ The quantities of complexing agents that need to be applied also depend on their active content. The Trilon M liquid (Trilon M sv, TRILON M LIQUID) have a higher active content than many competitors’ products because they contain fewer by-products. Inhibiting calcium carbonate Phosphonates and water-soluble polymers are often used to prevent scale calcium carbonate from precipitating and forming scale. These substances act by temporarily delaying the onset of crystallisation. Chelating agents such as the Trilon M liquid (Trilon M sv, TRILON M LIQUID) act differently, because they prevent salts from precipitating and forming scale by sequestering the calcium ions. Scale can form if phosphonates or water-soluble polymers are used, depending on the concentrations of calcium ions and polymer or phosphonates, because the calcium ions do not form permanent bonds.

➔ The Trilon M liquid (Trilon M sv, TRILON M LIQUID) can be used to boost the action of polyacrylates and phosphonates in inhibiting scale formation. They can enhance the overall performance of scale inhibitor formulations. There is a need for phosphonates to be replaced in many applications because of issues concerning the effects of phosphorus compounds on aquatic life and water quality. Aminocarboxylates often perform better at a high pH, but phosphonates perform better at a low pH because they are more soluble than many aminocarboxylates. The solubility of the Trilon M liquid (Trilon M sv, TRILON M LIQUID) at a low pH is very good and they are quite capable of competing with phosphonates.

The Trilon M liquid (Trilon M sv, TRILON M LIQUID) are an effective alternative to EDTA for removing calcium phosphate scale. The high performance of EDTA remains unsurpassed, but the performance of the Trilon M liquid (Trilon M sv, TRILON M LIQUID) is by far the best of all of the readily biodegradable complexing agents. Weak complexing agents such as iminodisuccinate (IDS), ethylenediaminedisuccinate (EDDS), hydroxyethyliminodiacetate (HEIDA) and citrate are completely ineffective for dissolving stubborn calcium phosphate scale.

➔ The Trilon M liquid (Trilon M sv, TRILON M LIQUID) are the best choice when it comes to finding a readily biodegradable complexing agent for dissolving calcium phosphate scale.

Organic scale Calcium stearate and calcium oleate (lime soaps)

Fatty acids and soaps also react with calcium ions to form sparingly soluble deposits in the kitchen, in the bathroom and on textiles. Lime, magnesium and heavy metals can form soaps that precipitate and give rise to spots and stains, dull surfaces, a rancid odour and poor wettability. They can also cause uneven dyeing, turbidity and changes in colour and cause rubber to perish. The Trilon M liquid (Trilon M sv, TRILON M LIQUID) are very effective for dissolving the scale formed by lime soaps and preventing scale from building up, and they are much more effective than weak complexing agents such as IDS or HEIDA. The Trilon M liquid (Trilon M sv, TRILON M LIQUID) can be used to stabilise bleach. They prevent hydrogen peroxide decomposing too quickly by sequestering iron, manganese and copper ions. The Trilon M liquid (Trilon M sv, TRILON M LIQUID) are an effective alternative to established bleach stabilisers such as EDTA, but the performance of EDTA is still unsurpassed. If local restrictions prevent EDTA from being used, the Trilon M liquid (Trilon M sv, TRILON M LIQUID) and Trilon P Liquid supplied by BASF are effective alternatives for stabilising bleach. Trilon M liquid (Trilon M sv, TRILON M LIQUID) is an inherently bioeliminable complexing agent that can also be used in combination with the Trilon M liquid (Trilon M sv, TRILON M LIQUID) to sequester iron, manganese and copper ions.

We know of no ill effects that could have resulted from using the Trilon M liquid (Trilon M sv, TRILON M LIQUID) for the purpose for which they are intended and from

processing them in accordance with current practice. According to the experience we have gained over many years and other information at our disposal, the Trilon M liquid (Trilon M sv, TRILON M LIQUID) do not exert any harmful effects on health, provided that they are used properly, due attention is given to the precautions necessary for handling chemicals, and the information and advice given in our Safety Data Sheets are observed.

Storage Trilon M liquid (Trilon M sv, TRILON M LIQUID) should not be stored at temperatures below 0 °C, because this can cause them to precipitate. It can be reconstituted by heating it briefly to 40 – 50 °C and stirring. Trilon M Powder is hygroscopic, and so it should be kept in tightly sealed containers.

The Trilon M liquid (Trilon M sv, TRILON M LIQUID) have a shelf life of one year in their tightly sealed original packaging. We would recommend storing Trilon M liquid (Trilon M sv, TRILON M LIQUID) in tanks made from AISI 316 Ti or AISI 321 stainless steel. Ecology and toxicology The Trilon M liquid (Trilon M sv, TRILON M LIQUID) have an excellent ecological and toxicological profile and there are no restrictions on their use in many applications. The active ingredient contained in the Trilon M liquid (Trilon M sv, TRILON M LIQUID), MGDA, is classified as being readily biodegradable according to the OECD criteria. In these tests, the test substance is broken down by bacteria under standardised conditions.

➔ The Trilon M liquid (Trilon M sv, TRILON M LIQUID) are classified as being readily biodegradable. The products supplied by BASF conform to ecological and toxicological stringent standards in order to protect the environment. BASF has submitted the Trilon M liquid (Trilon M sv, TRILON M LIQUID) to a thorough programme of tests and possesses a very extensive collection of data on the Trilon M liquid (Trilon M sv, TRILON M LIQUID).

Trilon M Liquide

Trilon M liquide (Trilon M sv, Trilon M liquid) T est une solution aqueuse du sel trisodique de l’acide méthylglycinediacétique (Na3MGDA). Il trouve une application dans les détergents, le nettoyage, les textiles, le savon, le placage de métal, le pétrole et le gaz et les produits adoucissants de l’eau. Le Trilon M liquide (Trilon M sv, Trilon M liquid) est facilement biodégradable.

Trilon M liquide (Trilon M sv, Trilon M liquid), sel trisodique d’acide méthylglycinediacétique (MGDA-Na3) ou diacétate d’α-DL-alanine trisodique (α-ADA), est l’anion trisodique de l’acide N- (1-carboxyéthyl) iminodiacétique et d’un agent complexant tétradentate. Il forme des complexes chélates stables 1: 1 avec des cations ayant un nombre de charges d’au moins +2, par ex. les cations “formant eau dure” Ca2 + ou Mg2 +. L’α-ADA se distingue de l’acide β-alaninediacétique isomérique par une meilleure biodégradabilité et donc une meilleure compatibilité environnementale.

Production de Trilon M liquide (Trilon M sv, Trilon M liquid)

La littérature des brevets sur la synthèse industrielle du Trilon M liquide (Trilon M sv, Trilon M liquid) décrit les approches pour résoudre les exigences clés d’un processus de fabrication pouvant être mis en œuvre à l’échelle industrielle, caractérisée par

Atteindre les rendements spatio-temporels les plus élevés possibles

Contrôle de réaction simple à des pressions et des températures relativement basses

Réalisation d’options de processus en continu

Atteindre les niveaux d’impuretés les plus bas possibles, en particulier l’acide nitrilotriacétique, soupçonné d’être cancérigène

Utilisation de matières premières peu coûteuses, par ex. au lieu de la L-alanine pure, le mélange brut de synthèse Strecker à partir de méthanal, de cyanure d’hydrogène et d’ammoniac

Éviter les étapes d’isolement complexes et réductrices de rendement; à la place, utiliser davantage les solutions réactionnelles brutes ou les précipités dans l’étape de procédé suivante.

Une voie de synthèse évidente de l’acide α-alaninediacétique est de l’α-DL-alanine racémique, qui fournit de l’α-ADA racémique par double cyanométhylation avec du méthanal et du cyanure d’hydrogène, l’hydrolyse du diacétonitrile formé de manière intermédiaire en sel trisodique et l’acidification ultérieure avec des acides minéraux dans un rendement global de 97,4%. [4] Dans une description de brevet ultérieure, cependant, seuls un rendement global de 77% et une teneur en NTA de 0,1% sont obtenus avec pratiquement les mêmes quantités de substances et dans des conditions de réaction pratiquement identiques.

MGDA Alanin

Cette dernière spécification de brevet indique également une voie de procédé via l’alaninonitrile, qui est obtenu par synthèse Strecker à partir de cyanure d’hydrogène, d’ammoniac et de méthanal et converti en méthylglycinonitrile-N, N-diacétonitrile par double cyanométhylation (étape 1). Les trois groupements nitrile sont ensuite hydrolysés avec de la soude en α-ADA (étape 2). Le rendement total est de 72%, la teneur en NTA de 0,07%.

MGDA Alaninonitril

Une variante de la réaction implique l’iminodiacétonitrile ou l’acide iminodiacétique (étape 1 ‘), qui réagit en milieu faiblement acide (pH 6) avec du cyanure d’hydrogène et de l’éthanal pour former de l’acide méthylglycinonitrile-N, N-diacétique dont le groupe nitrile est hydrolysé avec de l’hydroxyde de sodium au Trilon M liquide (Trilon M sv, Trilon M liquid) (étape 2 ‘) Le réactif acide iminodiacétique est accessible à faible coût par déshydrogénation de la diéthanolamine. Là encore, le rendement total est de 72%, la teneur en NTA de 0,07%.

Une autre variante convient à la production continue, dans laquelle l’ammoniac, le méthanal et le cyanure d’hydrogène réagissent à pH 6 pour former de l’iminodiacétonitrile, qui dans un milieu fortement acide (pH 1,5) réagit avec l’éthanal pour produire du trinitrile méthylglycinonitrile-N, N-diacétonitrile dans un très bon rendement de 92%. (étape 1).

MGDA Iminodiacetonitril

L’hydrolyse alcaline (étape 2) donne un rendement total de 85% de Trilon M liquide (Trilon M sv, Trilon M liquid) avec une teneur en NTA de 0,08%. Cette variante de procédé semble remplir au mieux les critères mentionnés ci-dessus.

Une voie de synthèse à faible sous-produit pour Trilon M liquide (Trilon M sv, Trilon M liquid) a récemment été décrite, dans laquelle l’alanine est éthoxylée avec de l’oxyde d’éthylène dans un autoclave pour former de la bis-hydroxyéthylaminoalanine, puis oxydée en α-ADA à 190 ° C avec du cuivre de Raney sous pression. [ 6]

MGDA Ethoxylierung

Les rendements sont supérieurs à 90% d.Th., les teneurs en NTA inférieures à 1%. Les conditions du procédé rendent cette variante un peu moins attractive.

Propriétés du Trilon M liquide (Trilon M sv, Trilon M liquid)

Le Trilon M liquide (Trilon M sv, Trilon M liquid) disponible dans le commerce (84% en poids) est un solide incolore, hydrosoluble dont les solutions aqueuses sont rapidement et complètement dégradées même par des bactéries non adaptées. La toxicité aquatique pour les poissons, les daphnies et les algues est faible. [7] Le Trilon M liquide (Trilon M sv, Trilon M liquid) est décrit comme facilement biodégradable (OCDE 301C) et est éliminé à plus de 90% dans les stations d’épuration des eaux usées. [8] Le Trilon M liquide (Trilon M sv, Trilon M liquid) n’a pas encore été détecté dans les rejets des stations d’épuration municipales et industrielles. Outre leur très bonne biodégradabilité, les solutions Trilon M liquide (Trilon M sv, Trilon M liquid) se caractérisent par une stabilité chimique élevée même à des températures supérieures à 200 ° C (sous pression) dans une large gamme de pH entre 2 et 14 ainsi qu’une stabilité complexe élevée par rapport à d’autres agents complexants de le type aminopolycarboxylate.

Les constantes de formation complexes des chélateurs biodégradables α-ADA et IDS se situent dans une plage adaptée à une utilisation industrielle, mais nettement en dessous de celles de l’EDTA standard précédent.

Dans les préparations solides, le Trilon M liquide (Trilon M sv, Trilon M liquid) est stable contre les agents oxydants tels que les perborates et les percarbonates, mais pas contre les acides oxydants ou l’hypochlorite de sodium.

Utilisation du Trilon M liquide (Trilon M sv, Trilon M liquid)

Comme d’autres agents complexants de la classe des acides aminopolycarboxyliques, le Trilon M liquide (Trilon M sv, Trilon M liquid) (α-ADA) se trouve en raison de sa capacité à former des complexes chélates stables avec des ions polyvalents (en particulier les agents de durcissement de l’eau Ca2 + et Mg2 +, ainsi que des ions de transition et de métaux lourds tels que Fe3 +, Mn2 +, Cu2 +, etc.) utilisé dans l’adoucissement de l’eau, dans les détergents et agents de nettoyage, dans la galvanoplastie, la cosmétique, la production de papier et de textile. En raison de sa stabilité à des températures et des valeurs de pH élevées, l’α-ADA devrait être particulièrement adapté comme substitut aux phosphates interdits dans l’UE à partir de 2017, tels que le tripolyphosphate de sodium (STPP) [12] dans les tablettes pour lave-vaisselle.

BASF SE est le plus important fabricant d’α-ADA sous la marque Trilon M liquid, possède des usines à grande échelle à Ludwigshafen et Lima, Ohio, et étend actuellement ses capacités existantes avec une autre usine à grande échelle sur le site d’Evonik à Théodore, Alabama.

Description du Trilon M liquide (Trilon M sv, Trilon M liquid)

Le Trilon M liquide (Trilon M sv, Trilon M liquid) est un agent chélatant qui offre une alternative non toxique et écologique aux phosphates et autres chélates puissants. L’acide méthylglycinediacétique (MGDA) est l’ingrédient actif et dépasse les produits alternatifs, comme les citrates, pour éliminer le tartre et les taches tenaces. Dissolvez efficacement les dépôts inorganiques et les écailles qui produisent des effets indésirables tels que des coups et des taches dans les applications de lave-vaisselle et de surfaces dures ou limitent les performances des surfactants et autres additifs dans les nettoyants et détergents.

L’agent chélateur Trilon M liquide (Trilon M sv, Trilon M liquid) améliore les performances de nettoyage des surfaces dures, des lave-vaisselle automatiques et des opérations de blanchisserie. Les clients d’I & l peuvent utiliser des concentrations plus faibles, en raison de son faible poids moléculaire, de cet agent complexant puissant dans leurs formulations de nettoyage, ce qui le rend plus rentable. Ce produit est efficace dans les nettoyants alcalins et acides, et démontre également une capacité de nettoyage efficace dans une variété d’applications, y compris les nettoyants à usage général, les produits d’entretien des sols, les détergents pour le lavage de la vaisselle, les désinfectants et assainissants, les détergents à lessive, les lave-vaisselle automatiques, les aides au lavage des véhicules et nettoyants pour les mains.

Le Trilon M liquide (Trilon M sv, Trilon M liquid) est extrêmement efficace dans la lutte contre l’eau dure et permet d’obtenir les meilleures performances de nettoyage. Dans les formules avec des tensioactifs anioniques, il est particulièrement important d’avoir un agent chélatant efficace comme le Trilon M liquide (Trilon M sv, Trilon M liquid), en particulier dans des conditions d’eau dure. D’autres agents chélateurs ne fonctionnent tout simplement pas aussi bien, et sans l’ajout d’un seul, il n’y a pratiquement aucun nettoyage indiqué.

Les Trilon M liquide (Trilon M sv, Trilon M liquid) sont des agents complexants très efficaces pour

calcium dans la gamme de pH alcalin. C’est un avantage dans de nombreux

applications détergentes et nettoyantes.

➔ Le Trilon M liquide (Trilon M sv, Trilon M liquid) est moins susceptible de cristalliser dans le pH acide

gamme que d’autres acides aminocarboxyliques, et ils sont toujours capables

de complexation efficace des ions de fer dans la plage de pH 2 à 3.

Comparaison avec les agents complexants faibles:

Les agents complexants faibles sont incapables de réduire la concentration d’ions métalliques libres dans les systèmes aqueux dans la même mesure que le Trilon M liquide (Trilon M sv, Trilon M liquid),

et le résultat est qu’ils sont incapables d’empêcher les ions métalliques de jouer un

rôle perturbateur dans les processus chimiques.

Les Trilon M liquide (Trilon M sv, Trilon M liquid) sont chimiquement très stables.

Le Trilon M liquide (Trilon M sv, Trilon M liquid) s’est révélé très stable par rapport à d’autres agents complexants organiques tels que l’acide citrique, l’acide tartrique et les gluconates,

surtout à des températures élevées.

Alors que les agents séquestrants inorganiques (par exemple les phosphates) peuvent s’hydrolyser à des températures élevées, le Trilon M liquide (Trilon M sv, Trilon M liquid) est stable – même lorsqu’il est chauffé à 200 ° C sous pression. La poudre Trilon M et les granules Trilon M commencent à se décomposer à env. 300 ° C.

Le Trilon M liquide (Trilon M sv, Trilon M liquid) résiste aux acides forts et aux bases fortes. Ils sont progressivement dégradés par l’acide chromique, le permanganate de potassium et d’autres agents oxydants puissants. La stabilité en présence de peroxyde d’hydrogène, de percarbonate et de perborate est suffisante pour une application conjointe. Néanmoins, nous ne recommandons pas de combiner Trilon M liquide (Trilon M sv, Trilon M liquid) et peroxydes dans des formulations liquides.

L’hypochlorite de sodium et d’autres substances qui libèrent du chlore provoquent la décomposition du Trilon M liquide (Trilon M sv, Trilon M liquid). Les complexes alcalino-terreux et de métaux lourds sont décomposés.

➔ Les formulations qui contiennent des agents complexants doivent rester chimiquement inchangées pendant le stockage et pendant le transport afin de pouvoir déployer leur pleine action. De nombreux agents complexants facilement biodégradables tels que les iminodisuccinates (IDS) et les citrates ne sont pas suffisamment stables. Le Trilon M liquide (Trilon M sv, Trilon M liquid) a une excellente stabilité chimique dans une large gamme de conditions, ce qui garantit que les formulations contenant du Trilon M liquide (Trilon M sv, Trilon M liquid) restent efficaces pendant de longues périodes. Stabilité du pH Le Trilon M liquide (Trilon M sv, Trilon M liquid) résiste à la dégradation sur toute la plage de pH 2 à 14, même à des températures élevées. Par exemple, les formulations qui contiennent du Trilon M liquide (Trilon M sv, Trilon M liquid) et des concentrations élevées d’hydroxyde de sodium restent stables et ne précipitent pas. D’autres agents complexants facilement biodégradables tels que l’iminodisuccinate précipitent en milieu alcalin, et ces agents complexants faibles ne sont alors plus capables de maintenir les ions métalliques en solution.

La miscibilité et la stabilité du Trilon M liquide (Trilon M sv, Trilon M liquid) sont excellentes, même dans des solutions très acides. De nombreux agents complexants ne peuvent pas être employés dans des formulations acides car ils précipitent sous la forme de leurs acides libres peu solubles. Le Trilon M liquide (Trilon M sv, Trilon M liquid) présente l’avantage de rester soluble et chimiquement stable, même dans la plage de pH acide.

➔ Le Trilon M liquide (Trilon M sv, Trilon M liquid) améliore les performances des formulations hautement alcalines.

➔ Le Trilon M liquide (Trilon M sv, Trilon M liquid) peut également être utilisé dans des formulations acides.

➔ Le Trilon M liquide (Trilon M sv, Trilon M liquid) ne se décompose pas même à un pH extrême.

Corrosion Le Trilon M liquide (Trilon M sv, Trilon M liquid) stabilise les ions métalliques polyvalents, ce qui signifie qu’ils peuvent augmenter la vitesse de dissolution des métaux. Néanmoins, à l’exception de l’aluminium, un agent oxydant tel que l’air doit toujours être présent pour que la corrosion se produise. L’acier non allié est sujet à la corrosion dans les milieux contenant de l’air, mais la corrosion peut être considérablement réduite si le pH est dans la plage alcaline et peut être éliminée presque complètement si l’oxygène et les autres agents oxydants sont exclus. L’acier nettoyé avec le Trilon M liquide (Trilon M sv, Trilon M liquid) dans la plage légèrement alcaline, qui est la plage de pH optimale pour le Trilon M liquide (Trilon M sv, Trilon M liquid), est beaucoup moins sujet à la corrosion que s’il est nettoyé avec des acides.

Le seul type de corrosion qui a été observé avec le Trilon M liquide (Trilon M sv, Trilon M liquid) est la corrosion uniforme: des piqûres ou fissures sous contrainte n’ont pas été observées dans

milieux à faible teneur en chlorure. L’un des avantages du Trilon M liquide (Trilon M sv, Trilon M liquid) est qu’il peut être fourni avec une très faible teneur en chlorure (<20 mg / kg). Les informations suivantes sur les matériaux sont de nature très générale, car la corrosion dépend de nombreux facteurs différents tels que l’exposition à l’air, la corrosion galvanique causée par la présence de différents métaux et par les schémas d’écoulement des liquides. La compatibilité du Trilon M liquide (Trilon M sv, Trilon M liquid) avec différents matériaux doit être testée dans chaque cas individuel.

Les aciers inoxydables austénitiques tels que AISI / SAE 304, 316 Ti et 321 sont très efficaces pour les récipients utilisés pour stocker et transporter Trilon M. Liquid. La résistance à la corrosion de l’acier au carbone ferritique tel que ASTM A201 Grade B (matériau européen n ° P265GH) est limitée. Un taux de corrosion de 0,01 mm / a a été mesuré à 50 ° C et exclusion d’air. Une corrosion caverneuse a également été observée à l’occasion sur les joints soudés, et nous ne recommandons donc pas de stocker le Trilon M liquide (Trilon M sv, Trilon M liquid) dans des récipients en acier au carbone non allié pendant une durée prolongée. Le taux de corrosion peut être réduit de

éliminer l’air du système.

Les alliages d’aluminium et d’aluminium tels que l’AL 7075 T6 (matériau européen n ° 3.4365) ne résistent pas au Trilon M Liquid, car le Trilon M Liquid est alcalin et l’aluminium est rapidement corrodé par les bases fortes. Les solutions contenant du Trilon M liquide (Trilon M sv, Trilon M liquid) sont beaucoup moins corrosives pour l’aluminium si leur pH est ajusté à 5 – 7. Les points suivants doivent être pris en compte lors de la comparaison des performances du Trilon M liquide (Trilon M sv, Trilon M liquid) avec des agents complexants plus faibles.

➔ La quantité d’agent complexant nécessaire pour séquestrer une concentration donnée d’ions calcium dépend de la force de l’agent complexant. Le Trilon M liquide (Trilon M sv, Trilon M liquid) a une action complexante plus efficace, et des quantités beaucoup plus petites sont nécessaires pour obtenir le même effet qu’avec l’IDS.

➔ Les quantités d’agents complexants à appliquer dépendent également de leur contenu actif. Le Trilon M liquide (Trilon M sv, Trilon M liquid) a un contenu actif plus élevé que les produits de nombreux concurrents car ils contiennent moins de sous-produits. Inhibition du carbonate de calcium Les phosphonates et les polymères hydrosolubles sont souvent utilisés pour empêcher le carbonate de calcium calcaire de précipiter et de former du tartre. Ces substances agissent en retardant temporairement le début de la cristallisation. Les agents chélateurs tels que le Trilon M liquide (Trilon M sv, Trilon M liquid) agissent différemment, car ils empêchent les sels de précipiter et de former du tartre en séquestrant les ions calcium. Du tartre peut se former si des phosphonates ou des polymères hydrosolubles sont utilisés, en fonction des concentrations d’ions calcium et de polymère ou de phosphonates, car les ions calcium ne forment pas de liaisons permanentes.

➔ Le Trilon M liquide (Trilon M sv, Trilon M liquid) peut être utilisé pour renforcer l’action des polyacrylates et des phosphonates dans l’inhibition de la formation de tartre. Ils peuvent améliorer les performances globales des formulations d’inhibiteurs de tartre. Il est nécessaire de remplacer les phosphonates dans de nombreuses applications en raison de problèmes concernant les effets des composés du phosphore sur la vie aquatique et la qualité de l’eau. Les aminocarboxylates fonctionnent souvent mieux à un pH élevé, mais les phosphonates fonctionnent mieux à un pH bas car ils sont plus solubles que de nombreux aminocarboxylates. La solubilité du Trilon M liquide (Trilon M sv, Trilon M liquid) à pH bas est très bonne et ils sont tout à fait capables de rivaliser avec les phosphonates.

Le Trilon M liquide (Trilon M sv, Trilon M liquid) est une alternative efficace à l’EDTA pour éliminer le tartre de phosphate de calcium. La haute performance de l’EDTA reste inégalée, mais la performance du Trilon M liquide (Trilon M sv, Trilon M liquid) est de loin la meilleure de tous les agents complexants facilement biodégradables. Les agents complexants faibles tels que l’iminodisuccinate (IDS), l’éthylènediaminedisuccinate (EDDS), l’hydroxyéthyliminodiacétate (HEIDA) et le citrate sont totalement inefficaces pour dissoudre le tartre de phosphate de calcium tenace.

➔ Le Trilon M liquide (Trilon M sv, Trilon M liquid) est le meilleur choix lorsqu’il s’agit de trouver un agent complexant facilement biodégradable pour dissoudre le tartre de phosphate de calcium.

Calamine organique Stéarate de calcium et oléate de calcium (savons à la chaux)

Les acides gras et les savons réagissent également avec les ions calcium pour former des dépôts peu solubles dans la cuisine, dans la salle de bain et sur les textiles. La chaux, le magnésium et les métaux lourds peuvent former des savons qui précipitent et donnent lieu à des taches et des taches, des surfaces ternes, une odeur rance et une mauvaise mouillabilité. Ils peuvent également provoquer une teinture inégale, une turbidité et des changements de couleur et faire périr le caoutchouc. Les Trilon M liquide (Trilon M sv, Trilon M liquid) sont très efficaces pour dissoudre le tartre formé par les savons à la chaux et empêcher l’accumulation de tartre, et ils sont beaucoup plus efficaces que les agents complexants faibles tels que IDS ou HEIDA. Le Trilon M liquide (Trilon M sv, Trilon M liquid) peut être utilisé pour stabiliser l’eau de Javel. Ils empêchent le peroxyde d’hydrogène de se décomposer trop rapidement en séquestrant les ions fer, manganèse et cuivre. Le Trilon M liquide (Trilon M sv, Trilon M liquid) est une alternative efficace aux stabilisants de blanchiment établis tels que l’EDTA, mais les performances de l’EDTA sont toujours inégalées. Si des restrictions locales empêchent l’utilisation de l’EDTA, le Trilon M liquide (Trilon M sv, Trilon M liquid) et le liquide Trilon P fournis par BASF sont des alternatives efficaces pour stabiliser l’eau de Javel. Trilon M Liquid est un agent complexant intrinsèquement bioéliminable qui peut également être utilisé en combinaison avec le Trilon M liquide (Trilon M sv, Trilon M liquid) pour séquestrer les ions fer, manganèse et cuivre.

Nous ne connaissons aucun effet néfaste qui aurait pu résulter de l’utilisation du Trilon M liquide (Trilon M sv, Trilon M liquid) aux fins pour lesquelles ils sont destinés et de

les traiter conformément à la pratique actuelle. D’après l’expérience que nous avons acquise depuis de nombreuses années et d’autres informations à notre disposition, le Trilon M liquide (Trilon M sv, Trilon M liquid) n’exerce aucun effet nocif sur la santé, à condition qu’il soit utilisé correctement, une attention particulière soit accordée aux précautions nécessaires à la manipulation des produits chimiques, et les informations et conseils donnés dans nos fiches de données de sécurité sont respectés.

Stockage Trilon M Liquid ne doit pas être stocké à des températures inférieures à 0 ° C, car cela peut provoquer leur précipitation. Il peut être reconstitué en le chauffant brièvement à 40 – 50 ° C et en agitant. La poudre Trilon M est hygroscopique et doit donc être conservée dans des récipients hermétiquement fermés.

Les Trilon M liquide (Trilon M sv, Trilon M liquid) ont une durée de conservation d’un an dans leur emballage d’origine hermétiquement fermé. Nous vous recommandons de stocker le Trilon M Liquid dans des réservoirs en acier inoxydable AISI 316 Ti ou AISI 321. Ecologie et toxicologie Les Trilon M liquide (Trilon M sv, Trilon M liquid) ont un excellent profil écologique et toxicologique et il n’y a aucune restriction sur leur utilisation dans de nombreuses applications. L’ingrédient actif contenu dans le Trilon M liquide (Trilon M sv, Trilon M liquid), MGDA, est classé comme étant facilement biodégradable selon les critères de l’OCDE. Dans ces tests, la substance d’essai est décomposée par des bactéries dans des conditions standardisées.

➔ Les Trilon M liquide (Trilon M sv, Trilon M liquid) sont classés comme étant facilement biodégradables.
