Description

HPAA (2-Hydroxyphosphonocarboxylic Acid)

(via rita at thwater dot com to make inquiry for it)

CAS 23783-26-8

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 of HPAA: Dark umber transparent viscous liquid
Solid content of HPAA : 47.0-50.0 percent
Phosphorous acid of HPAA (as PO33-): 4.0 percent max
Density of HPAA (20centigrade): 1.30 g/cm3 min
pH of HPAA (1percent 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.
