HPAA
ThFine
CAS No. 23783-26-8
2-Hydroxy Phosphonoacetic Acid
CAS No.: 23783-26-8 EINECS No.: 405-710-8
Molecular Formula: C2H5O6P Molecular Weight: 156
RIDADR: UN 3265 8/PG III
Structural Formula:
Properties:
HPAA has good chemical stability, hard to be hydrolyzed, and hard to be damaged by acid or alkali, safe and reliable to use, non-toxic and pollution-free. HPAA can improve the solubility of zinc, with strong inhibition, HPAA has better inhibition performance than HEDP, EDTMP. HPAA is mainly used as the cathodic corrosion inhibitor for metals, but also widely used to realize corrosion inhibition and scale inhibition in circulating cooling water system of steel, petrochemical, electric power, pharmaceutical and other industries. HPAA is specially suitable for low hardness and easy-corrosive water quality.
Specification:
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 |
pH(1% water solution) | 3.0 max |
Usage:
The organic corrosion inhibitors of which HPAA combines with low molecular weight polymer have excellent performance. When built with zinc salt, the effect is even better.
Package and Storage:
Normally in 200L HDPE drum, 1000L IBC, or customers’ requirement.
Storage for ten months in shady room and dry place.
Safety Protection:
Avoid contact with eye and skin, once contacted, flush with water.
Synonyms:
2-Hydroxy Phosphonoacetic Acid;
2-Hydroxyphosphonocarboxylic Acid;
Phosphonates Antiscalants, Corrosion Inhibitors and Chelating Agent
