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.

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.
