HPAA
|
CAS No.: 23783-26-8
|
Molecular Formula: C2H5O6P
|
|
Synonyms: HPA, Hydroxyphosphono-acetic Acid |
Molecular Weight: 156 |
Properties:
HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. It can improve zinc solubility. The corrosion inhibition ability of HPAA is 5-8 times better than that of HEDP and EDTMP.
