Phospono Butane Tricarboxylic Acid (PBTC)

2-Phosponobutane-1,2,4-Tricarboxylic Acid

PBTC 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. Its anti-scale property under high temperature is far better than that of organophosphates. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.

Molecular Formula : C7H11O9P

PBTC is a high efficient agent as scale and corrosion inhibitor. PBTC 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. PBTC 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.

PBTC is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.
