HPAA --2-Hydroxyphosphonocarb

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.
