Water Treatment Chemical Hydroxyphosphono-Acetic Acid (HPAA) CAS 23783-26-8

Water Treatment Chemical Hydroxyphosphono-Acetic Acid (HPAA)

Name: Hydroxyphosphono-acetic acid / HPAA

CAS: 23783-26-8

Chemical formula: C2H5O6P

Appearance: Dark Brown Liquid

Molecular weight : 156.03

HPAA is mainly used as a metal cathode corrosion inhibitor, widely used in steel, petrochemical, electric power, medicine and other industries of circulating cooling water system corrosion and scale inhibition, suitable for use as a low hardness, easy to corrode water corrosion inhibitor in southern China, and zinc salt compound effect is better.

HPAA Properties:

HPAA 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. 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.

HPAA Specification:

HPAA Application:

Hydroxyphosphono-Acetic Acid HPAA , is an important chemical substance whose application focuses on the following areas:

I. Water Treatment Field

HPAA has remarkable effect in the field of water treatment, mainly reflected in the following aspects:

*Corrosion inhibition: HPAA has an extremely strong corrosion inhibition, and its corrosion inhibition performance is better than HEDP, EDTMP and other common corrosion inhibitors. It can effectively prevent the corrosion of metal equipment in water and extend the service life of the equipment. It is especially suitable for use in low hardness, easy to corrode water quality in the south of China.

*Scale inhibition: HPAA can form stable complexes with calcium, magnesium and other hard water ions in water to prevent them from precipitating on the surface of pipelines, boilers and other equipment, thus preventing the formation of scale. In addition, HPAA can also significantly reduce the deposition of calcium carbonate, silica, with better scale inhibition performance.

*Dispersing effect: HPAA can also disperse the particulate matter in water, prevent it from precipitating and fixing on the metal surface, further protecting the metal equipment.

*Regulation of water quality: HPAA can regulate the pH value of the water to keep it in the proper range, preventing the water from being too high or too low in acidity or alkalinity and causing damage to the equipment.

II. Metal Treatment Field

HPAA is mainly used as cathodic corrosion inhibitor for metals, widely used in steel, petrochemical, electric power, pharmaceutical and other industries for circulating cooling water system corrosion and scale inhibition. It is more effective when used in combination with zinc salt, which can provide excellent corrosion and scale inhibition ability.

III. Safety and Protection

Despite the excellent performance of HPAA, the following points should be noted during use and storage:

HPAA is an acidic liquid, labor protection should be paid attention to during operation, avoiding direct contact with skin, eyes and so on. If contacted inadvertently, it should be immediately flushed with plenty of water and seek medical attention.

It should be stored in a cool place indoors, avoiding direct sunlight and high temperature environment. Ensure the package is intact and avoid leakage and contamination.

Ⅳ. Environmental Protection Characteristics

HPAA is biodegradable and will not pollute the environment, which is in line with the current green and environmental protection development trend.

In summary, Hydroxyphosphono-Acetic Acid (HPAA) in the field of water treatment, metal treatment and other areas with a wide range of prospects for application, its excellent performance and environmental characteristics make it an important chemical reagent in these areas.
