Hydroxyphosphono-acetic acid
CAS No. 23783-26-8
Molecular Formula: C2H5O6P Molecular weight: 156
Structural Formula:
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.
