Product Description

2-Hydroxy Phosphonoacetic Acid (HPAA)

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, 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.

Specification:

Items	Index
Appearance	Dark umber liquid
Solid content, %	50.0min
Total phosphonic acid (as PO₄^3-), %	25.0 min
Phosphoric acid (as PO₄^3-), %	1.50 max
Density (20℃), g/cm³	1.30 min
pH (1% water solution)	1.0-3.0

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.

Package and Storage:

200L plastic drum,IBC(1000L),customers’ requirement. Storage for one year in shady room and dry place.
