Organophosphoric Antiscale and Corrosion Inhibitors, Chelant

2-Hydroxy Phosphonoacetic Acid(HPAA)


CAS No. 23783-26-8

Molecular Formula: C2H5O6P

Molecular weight: 156

Structural Formula:

2-Hydroxyphosphonocarboxylic Acid (HPAA) Structural Formula

Properties:

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:
