I. Properties and uses:

Chaical properties: good stability, not easy to hydrolyse, acid and alkali resistance, safe and reliable, non-toxic and non-polluting.

Functional properties: improve zinc solubility, h3 corrosion inhibition, better performance than HEDP, EDTMP.

The Chinese name of HPAA, 2-hydroxyphosphonoacetic acid, is more widely used in the water treatment industry. It is an excellent corrosion inhibitor, which can be used to prevent metal corrosion and sediment formation in water. In addition, HPAA can be used in water treatment processes in petrochemical, textile, paper, leather and other industries.
It should be noted that HPAA is an organophosphate compound, which is toxic and irritating. In the process of use, care should be taken to avoid direct contact with skin and eyes, such as inadvertent contact, should be immediately flushed with large amounts of water, and promptly seek medical attention. In addition, HPAA should be stored in a cool, dry, well-ventilated place, avoiding contact with oxidising agents, acids and other substances to avoid dangerous reactions.

Main Ingredients:

The chemical name of HPAA is ethyl 2-hydroxyphosphate and its chemical formula is C2H7O6P.

Main Uses:

Corrosion inhibitor: HPAA can be used as a corrosion inhibitor for steel, copper, zinc and other metals. It can form a protective phosphate film with the metal surface and reduce the contact between the metal and the oxygen and moisture in the environment, thus playing the role of corrosion inhibition.

There are many kinds of water treatment agent scale and corrosion inhibitor class, both corrosion inhibition and scale inhibition function of the product are mainly:

Organic phosphorus corrosion inhibitors: such as ATMP, HEDP, DTPMPA, EDTMPS, HPAA and so on.

DTPMPA and DTPMPS are both phosphonate chemicals of the phosphonate condensation class, which are commonly used in water treatment, oil field development and other fields.

Their difference lies in their different chemical structures.

DTPMPA (diethylenetriaminepenta-methylphosphonic acid) and HEDP (hydroxyethylidene diphosphonic acid) differ in several aspects, and the following is a detailed analysis of the differences:

I. Basic properties

Second, the chemical structure and composition

• DTPMPA: is a compound containing multiple amino and phosphonic acid groups, with a complex molecular structure, which makes it able to form a variety of stable complexes in water, thus providing excellent scale and corrosion inhibition.
• HEDP: It is an organophosphonic acid compound with two phosphonic acid groups in its molecule, which can form stable complexes with metal ions (such as calcium ions) in water, thus playing the role of scale and corrosion inhibition.

Third, performance characteristics

1. Scale inhibition effect:

• DTPMPA has excellent performance in high temperature and alkaline environment, and its scale inhibition effect is especially significant for insoluble salts such as calcium carbonate.
• HEDP also has good scale inhibition effect, but compared to DTPMPA in some specific conditions of the scale inhibition effect may be more excellent.

Corrosion inhibition:

Diethylenetriamine PentaMethylenephosphonic Acid (DTPMPA) is a highly efficient and multifunctional chelating agent, which is widely used in the fields of water treatment, oilfield development, chemical industry, papermaking, textile, printing and dyeing, electronics, pharmaceuticals and so on. Its unique chemical structure and properties make it play an important role in several industries.

Diethylenetriaminepenta(methylenephosphonic acid) is abbreviated as DTPMPA, CAS number 15827-60-8, relative molecular weight 573.2.

DTPMPA is a widely used organophosphonic acid scale and corrosion inhibitor, which stands for diethylenetriamine penta (methylenephosphonic acid). It is frequently used in water treatment processes, particularly in industrial environments such as cooling water systems.DTPMPA helps prevent scale formation and corrosion in a variety of applications by chelating metal ions and dispersing solids. Its chemical structure and properties allow it to effectively control water hardness and improve the efficiency of water systems.

Diethylenetriamine PentaMethylene Phosphonic Acid (DTPMPA) is an organic phosphonate compound, also known as Diethylenetriamine PentaMethylene Phosphonic Acid. It is a multifunctional corrosion inhibitor, chelating agent and scale inhibitor, and is commonly used in water treatment, oilfield extraction, textile, paper making and other industrial fields.
