Product Details

Products Description of 2-Phosphonobutane-1,2,4-tricarboxylic acid CAS#37971-36-1

2-Phosphonobutane-1,2,4-tricarboxylic acid (PBTC) is the latest generation of internationally popular phosphonic acid. It is one of the most widely used and best-performing products in the compounding of high-efficiency scale and corrosion inhibitors. This product is particularly suitable for water conditions with high temperature, high hardness, high alkalinity, high pH, and high concentration ratio. It has good scale inhibition performance against calcium carbonate scale and phosphoric acid = calcium scale. It has low toxicity, low phosphorus content, good chemical stability, and excellent stable chelation effect on zinc salts. It has a good dispersing effect on water with high turbidity and high iron content. This product is generally used in combination with other water treatment agents such as zinc salts, copolymers, azoles, etc., and the single dosage is 5-15mg/L.

Product Application of 2-Phosphonobutane-1,2,4-tricarboxylic acid CAS#37971-36-1

PBTCA is the most widely used in the compounding of high-efficiency scale and corrosion inhibitors. It is one of the products with the best performance and is also an excellent stabilizer for zinc salts. It is widely used in the corrosion and scale inhibition of circulating cooling water systems and oilfield water injection systems. It is particularly suitable for compounding with zinc salts and copolymers. It can be used in high temperature, high hardness, high alkali and occasions that require high concentration multiples. PBTCA can be used as a chelating agent and metal cleaning agent in the washing industry. PBTCA is generally used in compounding with other water treatment agents such as zinc salts, copolymers, organic phosphine, azoles, etc.; if used alone, the dosage is 5~15mg/L.
