MOLECULAR FORMULA OF PBTCA; C7H11O9P
MOLECULAR WEIGHT OF PBTCA: 270.13 g/mol
PROPERTIES: PBTCA is a 50% aqueous solution of 2-phosphonobutane-1, 2, 4-tricarboxylic acid (PBTC) designed to control calcium scale formation and precipitation in highly stressed alkaline Industrial Water Treatment (IWT) and boiler systems. PBTCA has been widely used in industry as a sequestering agent and calcium carbonate scale inhibitor for applications in industrial water treatment and industrial cleaning. PBTCA is mainly used as Scale & Corrosion Inhibitor in Cooling, Boiler & Field Water Treatment. PBTCA has low content of phosphoric, has structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties. PBTCA’santiscale property under high temperature is far better than that of phosphonates. Phosphonate PBTCA can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy. Phosphonate PBTCA is a high efficient agent as scale and corrosion inhibitor. PBTCA is the excellent stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield refill water system as scale and corrosion inhibitor, suitable to composite with zinc salt and copolymer. PBTCA can be used in situations of high temperature, high hardness, high alkali and high concentration index. In lavation fields, it is used as chelating agent and metal detergent.
PBTCA is usually used together with zinc salt, copolymer, phosphonates, imidazole and otherWater Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.
2-Phosphonobutane-1,2,4-tricarboxylic acid (PBTCA) is an antiscalant that is widely used in reverse osmosis (RO) systems. Because of its high concentration in RO concentrate, eutrophication risk and anti-precipitation properties may affect subsequent treatments, therefore treatment strategies are needed to eliminate such substances. In this study, PBTCA was degraded by ozonation. The results show that PBTCA reacted with ozone molecules and hydroxyl radicals, with second-order rate constants of (0.12?±?0.002) and (7.83?±?1.51)?×?108?L?mol-1?s-1, respectively. The phosphorus in PBTCA (PP) was transformed into organic phosphorus except for PBTCA (PO), and inorganic phosphorus (PI); PO was further transformed into PI. The changes in the concentrations of these phosphorus forms were investigated by model simulation. Simulation showed that the rate of PP transformation into PO was 5.5 times higher than that into PI. PBTCA was ozonated much faster at alkaline pH than at acidic pH. This is ascribed to different amounts of ozone molecules and hydroxyl radicals, and their different reaction rates with PBTCA. Furthermore, anti-precipitation property was reduced during ozonation, as shown by the amounts and morphology changes of the precipitates. PBTCA concentration for 50% anti-precipitation (AP50) did not change during ozonation, indicating that the transformation products generated during ozonation did not have anti-precipitation effects. Phosphorus in PBTCA was removed by ozonation–coagulation treatment. Total phosphorus and inorganic phosphorus were removed efficiently by using ferric chloride as a coagulant. The coagulants tended to bind with inorganic phosphorus to form flocs. Meanwhile, flocs were more easily to aggregate and precipitate as anti-precipitation effect was gradually removed, thus more phosphorus was removed. A combination of ozonation and coagulation removed PBTCA effectively and simultaneously reduced its anti-precipitation property and phosphorus.

Whether PBTCA belongs to an environmentally-friendly scale inhibitor or not, many customers have this question when purchasing. Today IRO will talk about PBTCA. Before determining whether PBTC acid is an environmentally friendly scale inhibitor, it is necessary to talk about the types of scale inhibitors. So far, the types of scale inhibitors that are widely used in the water treatment industry are mainly the following. Organic phosphine scale inhibitor (phosphorus), organic phosphonate scale inhibitor (phosphorus), compound scale inhibitor, environmental scale inhibitor (PESA, PASP, etc.), low phosphorus-containing scale inhibitor (such as PBTCA).
Among the organic phosphine type scale inhibitors, PBTCA is one of the lowest scale inhibitors. The reason is that its structural characteristics contain only one phosphorus element in the molecular formula. At the same time, PBTC chemical has the characteristics of phosphonic acid and a carboxylic acid, which has good scale inhibition and corrosion inhibition performance and is much better than other organic phosphonic acid scale inhibitors.
PBTCA has low phosphorus content and is ideal for scale inhibition. Within the foreseeable range, PBTC acid is still the main product in water treatment chemicals and can be used as a compound or as a separate ingredient.
As the country’s environmental requirements become more stringent, the use of more water treatment agents with higher phosphorus content is limited. PBTC acid meets national environmental requirements. PBTCA is relatively affordable and is a good choice for most companies.
It is well known that organic phosphine water treatment agents are the most widely used in monomer water treatment agents. Faced with more environmental pressures, water treatment agents are moving towards diversification. For example, compounding, copolymer, polymer, and other water treatment agents are more targeted when used.
1. PBTCA has a much higher tolerance for Ca2+. It is used under the conditions of high hardness, high alkali, high temperature, high pH and high concentration. It can still achieve a good scale inhibition effect.
2. PBTCA has a high solubility in zinc salts and good stability. It can be combined with zinc salt to obtain a very good corrosion inhibition effect.
3. PBTCA has low phosphorus content (only 11-15%), and it has a low dosage and is not subject to environmental emissions. It is one of the more advanced circulating cooling water treatment chemicals in China.
4. Among the organic phosphine water treatment agents, PBTCA is one of the most suitable organic phosphine monomers for environmentally friendly scale inhibitors due to its own characteristics and low phosphorus content. PBTC acid has the structural properties common to phosphonic acids and carboxylic acids.
5. Therefore, it is relatively superior to other organic phosphonic acids, and it has excellent scale inhibition and corrosion inhibition properties. At the same time, PBTC chemical is resistant to high temperature and high alkali, and its scale inhibition performance at high temperature is much higher than other commonly used organic phosphines. PBTCA is also used as a special corrosion and scale inhibitor for high temperature.
6. PBTCA is the most widely used in the combination of high-efficiency corrosion and scale inhibitors. It is one of the best performance products among all known scale inhibitors. At the same time, PBTC has functional diversity. For example, PBTCA can also be used as a stabilizer for zinc salts. In addition, PBTCA can also be used as a chelating agent and metal cleaner in the washing industry.
7. PBTCA is currently mainly used for corrosion and scale inhibition of circulating cooling water systems and oilfield refill systems. PBTC acid is compounded with zinc salt and copolymer during use and is used for high temperature, high alkali, high hardness water quality.
PBTCA (2-Phosphonobutane -1,2,4-Tricarboxylic Acid)
PBTC; PBTCA; FOSFONOBUTANE TRICARBOXYLIC AST; 2-Fosfonobutan-1,2,4-Trikarboksilik Asit; 2-Fosfonobutan-1,2,4-trikarboksilik asit PBTCA; Phosphonates and phosphonic acids are organophosphorus compounds containing C-PO(OH)2 or C-PO(OR)2 groups (where R = alkyl, aryl). Phosphonic acids, typically handled as salts, are generally nonvolatile solids that are poorly soluble in organic solvents, but soluble in water and common alcohols. Many commercially important compounds are phosphonates, including glyphosate (the active molecule of the herbicide “Roundup”), and ethephon, a widely used plant growth regulator. Bisphosphonates are popular drugs for treatment of osteoporosis.[1]
Clodronic acid is a bisphosphonate (PBTCA) used as a drug to treat osteoporosis.
In biology and medicinal chemistry, phosphonate groups are used as stable bioisoteres for phosphate, such as in the antiviral nucleotide analogue, Tenofovir, one of the cornerstones of anti-HIV therapy.
