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.
