HPAA 2-Hydroxy Phosphonoacetic Acid
CAS No. 23783-26-8
Molecular Formula: C2H5O6P Molecular weight: 156
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.
Items Index Appearance Dark umber liquid Solid content, % 50.0min Total phosphonic acid (as PO43-), % 25.0 min Phosphoric acid (as PO43-), % 1.50 max Density (20℃), g/cm3 1.30 min pH (1% water solution) 1.0-3.0
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.
