Product Description

CAS No. 23783-26-8

Molecular Formula: C₂H₅O₆P

Molecular weight: 156

Structural Formula:

Properties:

HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safe in use, no toxicity, no pollution. HPAA can improve zinc solubility. Its corrosion inhibition ability is 5-8 times better than that of HEDP and EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better.

Specification:

Items	Index
Appearance	Dark umber liquid
Solid content %	50.0 min
Total phosphonic acid(as PO₄^3-)%	25.0 min
Phosphoric acid (as PO₄^3- )%	1.5 max

Usage:

HPAA is mainly used as a cathode corrosion inhibitor in oilfield refill water systems in fields such as steel & iron, petrochemical, power plant, and medical industries. When built with zinc salt, the effect is even better.
