PBTCA 2-phosphonate-1,2,4-tricarboxylate


PBTCA has low phosphorus content. Because of its structural characteristics of phosphonic acid and carboxylic acid, it has good scale inhibition and corrosion inhibition performance, which is superior to the commonly used organic phosphonic acid. Especially at high temperature, the scale inhibition performance is far superior to the commonly used organic phosphonic acid, which can improve the solubility of zinc, good chlorine resistance oxidation performance and good coordination of the compound.

PBTCA is widely used in the compounding of efficient scale and corrosion inhibitors, is one of the products with better performance, and is also an excellent stabilizer of zinc salts.


It is widely used in the circulating cooling water system and oil field water injection system for corrosion and scale inhibition, especially suitable for the use of zinc salts and copolymers in combination, and can be used in high temperature, high hardness, high alkali and occasions requiring high concentration ratio. PBTCA can be used as chelating agent and metal detergent in the washing industry.

Quality indicators:


Usage method:

PBTCA is generally used in combination with zinc salts, copolymers, organophosphorus, azoles and other water treatment agents.If used alone, the dosage is 5-15 mg/L.

Packaging and Storage:

The PBTCA plastic drums are packaged in 30Kg or 250Kg each and stored in a cool indoor place for one year.

Safety and protection:

PBTCA is acidic and should avoid contact with eyes and skin. Once splashed on the body, it should be rinsed with plenty of water immediately.
