HPAA Description
NAME: Hydroxy phosphonoacetic acid (HPAA)
Synonyms: 2-Hydroxy Phosphonoacetic Acid
Molecular Formula: C2H5O7P
Molecular weight: 156
CAS NO.: 23783-26-8
Density: 2.2±0.1 g/cm3
Boiling point: 515.4±60.0 °C at 760 mmHg
Melting point: 108-110ºC
Flashing point: 265.5±32.9 °C
Appearance: Dark brown liquid
Properties:
1. Hydroxy phosphonoacetic acid is chemically stable, hard to hydrolyze, hard to be destroyed by acid or alkali, safe in use, and has no toxicity and pollution. In addition, it can improve zinc solubility. It performs better than commonly used phosphonates like HEDP and EDTMP (5~8 times better).
2. Sometimes Hydroxy phosphonoacetic acid can even replace molybdate and its derivatives. The good efficiency at low concentrations enables it, usually used at the PPM level. Hydroxy phosphonoacetic acid is water-soluble and can increase Zn solubility. Its effect can be further improved when built with Zn salts or polymer.
Usage: The organic corrosion inhibitors of which Hydroxy phosphonoacetic acid combines with low molecular weight polymer have excellent performance. When built with zinc salt, the effect is even better.
Package : 200L plastic drum, IBC(1000L), customers’ requirement.
Storage:
1.Store in a cool and ventilated place, avoid direct sunlight. Can not be stored and transported with strong alkali, nitrite or sulfite and other substances.
2. Long-term storage, due to the impurities contained in it can release carbon dioxide, the pressure should be released regularly.
Safety protection: This product is acidic. Pay attention to labor protection during operation. Avoid contact with skin, eyes, etc. After contact, flush with plenty of water immediately.
About Us: With over many years as a certified HPAA & Hydroxy phosphonoacetic acid manufacturer, we combine innovation with stringent production standards to deliver high-performance product.
