  Detailed Description: 2-Hydroxyphosphonocarboxylic
Acid (HPAA)
CAS No 23783-26-8
Molecular Formula:
C2H5O6P
Molecular weight: 156

Properties of HPAA:
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 of HPAA:
Appearance Dark umber
transparent viscous liquid
Solid content % 47.0-50.0
Phosphorous acid(as PO33-)%
4.0 max
Density (20 C)g/cm3 1.30 min

pH(1% solution) 1.0-3.0

Usage of HPAA:
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 of HPAA:
Normally In 250kg net Plastic
Drum, IBC drum can also be used
as required. Storage for one year
in room shady and dry place.
