Hydroxyphosphono-acetic acid

CAS No.  23783-26-8

Molecular Formula:   C2H5O6P                  Molecular weight: 156

Structural Formula:

2-Hydroxyphosphonocarboxylic Acid (HPAA)

Properties:

Hydroxyphosphono-acetic acid is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. Hydroxyphosphono-acetic 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.

Specification:
