Water treatmnet chemical PBTCA

CAS No. 37971-36-1

Molecular Formula: C7H11O9P

Molecular weight: 270.13

Properties:

PBTCA has low content of phosphoric, has structural features of both phosphoric acid carboxylic acid group, which enable its excellent scale corrosion inhibition properties. Its antiscale property under high temperature is far better than that ofganophosphines. It can improve zinc salt solubility, has good chlorine oxidation tolerance good composite synergy.

Usage:

PTBCA is a high efficient agent as scale corrosion inhibitor. It is the excellent stabilizer fzinc salt. It is widely used in circulating cool water system oilfield refill water system as scale corrosion inhibitor, suitable to composite with zinc salt copolymer. It can be used in situations of high temperature, high hardness, high alkali high concentration index. In lavation fields, it is used as chelating agent metal detergent. PBTCA is usually used together with zinc salt, copolymer,ganophosphine, imidazole other Water Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.
