2-HYDROXY PHOSPHONOACETIC ACID

CAS No. 23783-26-8

Molecular Formula: C₂H₅O₆P Molecular weight: 156

Structural Formula:

2-Hydroxy Phosphonoacetic Acid (HPAA)

Properties:

2-HYDROXY PHOSPHONOACETIC ACID is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. 2-HYDROXY PHOSPHONOACETIC ACID 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.
