CAS 23783-26-8 Organic Phosphonic Acid,
HPAA Organic Phosphonic Acid,
Chemicals name: 2-Hydroxyphosphonocarboxylic Acid(HPAA)
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 effectis even better.
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.
Package and Storage:
Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for one year in room shady and dry place.
