Product Description

2-Hydroxy Phosphonoacetic Acid

HPAA

CAS No. 23783-26-8

Molecular Formula: C2H5O6P

Molecular weight: 156

Synonyms: Hydroxyphosphono-acetic Acid

Structural Formula:

Properties:

HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety 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.

Usage:

HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as

steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect

is even better.
