2-Hydroxy Phosphonoacetic Acid HPAA
CAS No: 23783-26-8
HS code 2931901990
UN NO 3265
EINIECS NO 229-146-5
Molecular Formula:C2H5O6P
Appearance:Dark umber liquid

Product Property 
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 EDTMPA.Na5. When built with low molecular polymers, its corrosion inhibition effect is even better.

Applications:
HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemical, power plant and medical industries. When built with zinc salt, the effect is even better.
