2-Hydroxy Phosphonoacetic 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 liquid |
| Solid content % | 50.0 min |
| Total phosphonic acid(as PO43-)% | 25.0 min |
| Phosphoric acid (as PO43- )% | 1.5 max |
| Density (20℃) g/cm3 | 1.30 min |

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.
