2-Acrylamido-2-methylpropane sulfonic acid (AMPS) was a Trademark name by The Lubrizol Corporation. It is a reactive, hydrophilic, sulfonic acid acrylic monomer used to alter the chemical properties of wide variety of anionic polymers. In the 1970s, the earliest patents using this monomer were filed for acrylic fiber manufacturing. Today, there are over several thousands patents and publications involving use of AMPS in many areas including water treatment, oil field, construction chemicals, hydrogels for medical applications, personal care products, emulsion coatings, adhesives, and rheology modifiers. ATBS Monomer And ATBS Sodium Salt are widely used in water treatment, acrylic fiber, oilfield, latex and adhesive, emulsion coatings, personal care and medical and construction applications. In the structure of the ATBS there are strong anion and water-soluble sulfur group, shield the amide group and the unsaturated double bond, these make the ATBS have the excellent performance. ATBS has the excellent synthesis, adsorptivity, biological activity, surface activity, hydrolytic stability and thermal stability. ATBS can be used in co-polymerization and in addition reaction, ATBS is widely used in water treatment, oilfield chemicals, chemical fiber, water absorbent material, plastics, paper making, spinning, printing and dyeing, biomedicine, magnetic material and makeup etc.ATBS Monomer And ATBS Sodium Salt for medium molecular weight polymer (AP3131G Granule and AP3132 Liquid) are especially effective in the following applications:Oil Field Applications: Due to their exceptional thermal and hydrolytic stability, AP3131G Granule and AP3132 Liquid are used in many oilfield applications where hostile environments demand high-performance products. Their unique hydrophilic nature, a tendency to increase viscosity and its divalent cation stability, also makes them the ideal solution for many oil field operations. In drilling operations, AP3131G Granule and AP3132 Liquid are used as scale inhibitors, friction reducers, non-retarding fluid loss control agent and water-control.Latex and Adhesive Applications: AP3131G Granule and AP3132 Liquid are field-proven to achieve exceptional latex stability in high-performance latex coatings. The dispersion of solids in aqueous media is colloidally stable, improving the preparation of high solids emulsions. It improves the thermal and mechanical properties of adhesives, and increases the adhesive strength of pressure-sensitive adhesive formulations. Lower molecular weight polymers containing ATBS Monomer And ATBS Sodium Salt are especially effective dispersants for highly polar materials.
PRODUCTION
AMPS is made by the Ritter reaction of acrylonitrile and isobutylene in the presence of sulfuric acid and water.[The recent patent literaturedescribes batch and continuous processes that produce AMPS in high purity (to 99.7%) and improved yield (up to 89%, based on isobutene) with the addition of liquid isobutene to an acrylonitrile / sulfuric acid / phosphoric acid mixture at 40°C.
PROPERTIES
Hydrolytic and thermal stability ATBS: The geminal dimethyl group and the sulfomethyl group combine to sterically hinder the amide functionality and provide both hydrolytic and thermal stabilities to AMPS-containing polymers.
Polarity and hydrophilicity ATBS: The sulfonate group gives the monomer a high degree of hydrophilicity and anionic character at wide range of pH. In addition, AMPS is absorbing water readily and also imparts enhanced water absorption and transport characteristics to polymers.
Solubility ATBS : AMPS is very soluble in water and dimethylformamide (DMF) and also shows limited solubility in most polar organic solvents.
APPLICATIONS
Acrylic fiber : A number of enhanced performance characteristics are imparted to acrylic, modified-acrylic, polypropylene and polyvinylidene fluoride fibers: dye receptivity, moisture absorbency, and static resistance.
Coating and adhesive : Its sulfonic acid group gives the monomers ionic character over a wide range of pH. Anionic charges from AMPS fixed on polymer particles enhance the chemical and shear stabilities of polymer emulsion and also reduce the amount of surfactants leaching out of paint film. It improves the thermal and mechanical properties of adhesives, and increases the adhesive strength of pressure-sensitive adhesive formulations.
Detergents: Enhances the washing performance of surfactants by binding multivalent cations and reducing dirt attachment.
Personal care: Strong polar and hydrophilic properties introduced to a high molecular weight AMPS homopolymer are exploited as a very efficient lubricant characteristic for skin care.
Medical hydrogel: High water-absorbing and swelling capacity when AMPS is introduced to a hydrogel are keys to medical applications. Hydrogel with AMPS showed uniform conductivity, low electrical impedance, cohesive strength, appropriate skin adhesion, and biocompatible and capable of repeated use and have been used to electrocardiograph (ECG) electrodes, defibrillation electrode, electrosurgical grounding pads, and iontophoretic drug delivery electrodes.In addition, polymers derived from AMPS are used as the absorbing hydrogel and the tackifier component of wound dressings. Is used due to its high water absorption and retention capability as a monomer in superabsorbents e. g. for baby diapers.
Oil field applications: Polymers in oil field applications have to stand hostile environments and require thermal and hydrolytic stability and the resistance to hard water containing metal ions. For example, in drilling operations where conditions of high salinity, high temperature and high pressure are present, AMPS copolymers can inhibit fluid loss and be used in oil field environments as scale inhibitors, friction reducers and water-control polymers, and in polymer flooding applications.
Water treatment applications: The cation stability of the AMPS-containing polymers are very useful for water treatment processes. Such polymers with low molecular weights cannot only inhibit calcium, magnesium, and silica scale in cooling towers and boilers, but also help corrosion control by dispersing iron oxide. When high molecular weight polymers are used, they can be used to precipitate solids in the treatment of industrial effluent stream.
Crop protection: increases in dissolved and nanoparticulatepolymer formulations bioavailability of pesticides in aqueous-organic formulations.
Membranes: It increases water flow, retention and fouling resistance of asymmetric ultrafiltration and microfiltration membranes and is being studied as an anionic component in polymer fuel cell membranes.
Construction applications: Superplasticizers with AMPS are used to reduce water in concrete formulations. Benefits of these additives include improved strength, improved workability, improved durability of cement mixtures. Redispersible polymer powder, when AMPS is introduced, in cement mixtures control air pore content and prevent agglomeration of powders during the spray-drying process from the powder manufacturing and storage. Coating formulations with AMPS-containing polymers prevent calcium ions from being formed as lime on concrete surface and improve the appearance and durability of coating.
ATBS is a unique vinyl polymer with a sulfonic acid group, and its polymers are used in a wide range of applications including textiles, flocculants, dispersants, scale inhibitors, additives for ore chutes, etc. As it is highly polymerizable, it can easily be copolymerized with acrylonitrile, acrylic acid, acrylic esters, and acrylamides using general methods. In 1999, Mr. Vinod Saraf, CMD of Vinati Organics Limited (VOL), approached Dr. Prashant Barve, Head, Process Development and Engineering Group at NCL to explore new opportunities in specialty chemical manufacture. Because of its numerous and diverse applications, ATBS was identified as one of the potential products. The challenge was to innovate a synthetic process that was commercially feasible and profitable. The NCL team not only successfully met this challenge but came up with a highly streamlined, continuous production method minimising the cost and the environmental impact. VOL is currently the largest manufacturer of ATBS worldwide. The NCL team has received 7 national awards to the day for their brilliant effort. A media report in September 2008 informed its readers, “NCL process puts Indian company in unique club”. Mumbai-based Vinati Organics Ltd had become the first manufacturer of ATBS, a specialty monomer, in the country. Acrylamido tertiary-butyl sulfonic acid (ATBS), also known as 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS®), is a specialty monomer used as co-monomer in numerous polymerization processes. It is used in the dye-pickup applications for synthetic fibres such as poly (acrylonitrile) fibers. It is also used in water treatment, construction chemicals, hydrogels for medical applications, personal care products, emulsion coatings, adhesives, and rheology modifiers. However, probably its most important application is in Enhanced Oil Recovery, where it is used in its highest possible purity grade. The technology to produce this speciality monomer was invented by Lubrizol more than 30 years ago. With their exceptionally high level of product purity, they were the global leader AMPS® production for a long time. Vinati Organics Limited (VOL) was established in 1989 by Mr. Vinod Saraf, an entrepreneur with a background in finance but open enough to venture into speciality chemical manufacture. For a while after its inception, VOL was a single chemical producing manufacturer. VOL was producing Isobutyl benzene, for use in manufacture of Ibuprofen, with a technology they received from Institut Français du Pétrole (IFP), France. However, VOL’s CMD, Mr. Vinod Saraf, was looking to expand Vinati’s product list beyond Isobutyl benzene. In 1999, he approached Dr. Prashant Barve, Head, Process Development and Engineering Group at NCL to explore other feasible and profitable production opportunities for VOL. Because of its numerous and diverse applications, AMPS® was identified as one of the potential products. If Dr. Barve’s team could innovate a novel process for production of AMPS® and if VOL could successfully commercialise it, Vinati Organics would become only the 3rd manufacturer worldwide of AMPS. However, the NCL-VOL team could not use the trade name ‘AMPS®’ for their new product because that was the registered trademark of Lubrizol. They, therefore, came up with the name ‘ATBS’ based on the other chemical name for the same molecule. It was mutually agreed between the NCL team and VOL to evaluate the feasibility of the process and produce a feasibility report for the same within following one year. Dr. Barve and his team found the manufacturing process to be moderately feasible and that there were not many takers for the product within the country. However, ATBS did have a global market. In July 2000, the NCL team demonstrated the manufacture of ATBS at the scale of 1kg. Considering the costs of the raw materials involved and the cost at which the global competitors were selling ATBS at, the process was rejected by VOL as non-feasible. By November of that year, Dr. Barve’s team tuned up the process in such a way that the raw material cost drastically reduced and the project became viable for VOL to go ahead with. The team also completed bascic engineering activity along with the process demonstration to VOL team. Around November 2000, VOL contracted Dalal Engineering Ltd. to come up with the detailed engineering package for the design and production of a plant that would be able to produce ATBS at industrial scale. With valuable inputs from Dr. Barve’s team, the plant was ready by July 2002 and testing began in order to streamline the process further. In October 2002, the plan spread over 25 acres, built to international safety standard and equipped with remote operation technology, was commissioned at Lote, Maharashtra. The plant is a flow reactor that manufactures ATBS in one continuous process from raw material stage to recovery and recycling of waste products to packaging of the finished product. NCL-VOL team has received much praise from their competitor Lubrizol for installing such a well-streamlined and compact plant. While Lubrizol is struggling with the recovery and recycling of acrylonitrile that has not been converted (85%), VOL is successfully utilising the recovery process invented by the NCL team. Due to their uniqueness, the plant and the recovery process have been patented by NCL. The monomers in the effluents from the process are polymerised and sold to the construction industry, thus minimising the environmental impact of the manufacturing process.With funding from the Technology Development Board (TDB) and investment from Mr. Saraf himself, the manufacture started at 3 tonnes per day, in October 2002. However, first couple of months were full of difficulties and the NCL-VOL team learnt a lot about the production of ATBS during this time. By December 2002, the production had been streamlined and first batches of commercially manufactured ATBS were shipped to VOL’s clients globally. Only acceptable ATBS for enhanced oil recovery application was the one with polymer weight higher than 4,00,000 amu. The team discovered that the chain transfer agent used in the manufacturing process was causing the polymer to be of lower molecular weight. Once appropriate changes were made, the NCL-VOL team was able to produce the polymer of required molecular weight. This commercial breakthrough in 2005 cleared the path for Vinati Organics to manufacture enhanced oil recovery grade ATBS. There has been a steady progress in the ATBS plant capacity at VOL since then.
