2-Hydroxyphosphonocarboxylic Acid (HPAA)
CAS No. 23783-26-8
Molecular Formula: C2H5O6P Molecular weight: 156
Structural Formula:

Properties:
2-Hydroxyphosphonocarboxylic Acid is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. 2-Hydroxyphosphonocarboxylic 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:
| items | index |
| Appearance | Dark umber transparent viscous liquid |
| Solid content % | 47.0-50.0 |
| Density (20℃)g/cm3 | 1.30 min |
| pH(1% solution) | 1.0-3.0 |
Usage:
2-Hydroxyphosphonocarboxylic Acid is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect is even better.
Package and Storage:
Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for one year in room shady and dry place.
