2-Hydroxy Phosphonoacetic Acid (HPAA)
Properties:
2-Hydroxy phosphonoacetic acid is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. 
HPAA can improve zinc solubility. 
HPAA has superior performance than those commonly used phosphonates like HEDP and EDTMP (5-8 times better).

Sometimes HPAA can even replace molybdate and its derivatives. 
The good efficiency at low concentration enables HPAA usually used at the PPM level. 
2-Hydroxy phosphonoacetic acid is water-soluble and can increase Zn solubility. 
Its effect can be further improved when built with Zn salts or polymer.

CAS No.: 23783-26-8

Molecular Formula: C2H5O6P


he main HPAA production route is as follows.

Phosphorus acid solution reacts with glyoxylic at 100-110°C for 4-10hours. And then input water to prepare HPAA aqueous solution. This reaction can be 1-step forward and starts from PCl3 hydrolysis.

Some research is studying to use microwave irradiation to replace the heating process for reducing energy consumption and reaction time.

Usage:
2-Hydroxy phosphonoacetic acid is mainly used as a cathode corrosion inhibitor in the oilfield refill water system in fields such as steel & iron, petrochemical, power plant, and medical industries.

When built with zinc salt, the effect is even better. 
As a corrosion inhibitor, 2-Hydroxy phosphonoacetic acid is mainly applied in the cooling water/industrial water system of oilfield, petrochemical plant and power plant. It is also used for metal surface treatment in steel.

HPA 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. 
HPA can improve the solubility of zinc, with strong inhibition, HPA has better inhibition performance than HEDP, EDTMP. 
HPA 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. 
HPA is specially suitable for low hardness and easy-corrosive water quality.

23783-26-8 
Name: 2-Hydroxyphosphonoacetic Acid
CAS: 23783-26-8;4721-24-8
Molecular Formula: C6H13O3P
Molecular Weight: 164.141

HPAA is an environmentally acceptable corrosion inhibitor for carbon steel in cooling water systems. 
HPAA gives better corrosion protection for carbon steel when used in conjunction with zinc or other phosphonates. 
HPAA reduces iron fouling, thus improving heat transfer efficiency and reducing system maintenance costs. 
HPAA is biodegradable and especially suitable in applications where the molybdate discharge is regulated OR all organic cooling water treatment is desired. 
It is expected to be susceptible to halogen attack.
