Aminotrimethylenephosphonic acid ATMP

Alias: Aminotrimethylenephosphonic acid, ATMPA, Nitrilotrimethylenetrisphosphonic acid, Nitrilotrimethylenephosphonic acid

【CAS】 6419-19-8      Molecular formula N(CH₂PO₃H₂)₃Relative molecular mass: 299.05     

I. Product Performance

ATMP has good chelating, threshold inhibition, and lattice distortion effects. It can prevent the formation of scale from scale-forming salts in water, especially calcium carbonate scale. ATMP is chemically stable in water and not easily hydrolyzed. At higher concentrations in water, it exhibits good corrosion inhibition effects.

II. Quality indicators comply with HG/T 2841-2005

III. Uses

ATMP is used in the circulating cooling water of thermal power plants and refineries, as well as in oilfield water injection systems. It can help reduce corrosion and scaling in metal equipment or pipelines. ATMP is used as a metal ion chelating agent in industries such as textile printing and dyeing, and can also be used in metal surface treatment agents.

ATMP is often compounded with other organic phosphonic acids, polycarboxylic acids, or salts to form organic alkaline water treatment agents, used in circulating cooling water systems under various water quality conditions. The optimal dosage is 1-20 mg/L; when used as a corrosion inhibitor, the dosage is 20-60 mg/L.

IV. Packaging and Storage

ATMP liquid is packaged in plastic drums, each containing 30 kg or 250 kg; it can also be customized according to user requirements. Store in a cool, ventilated indoor area, strictly avoid exposure to sunlight, with a storage period of ten months.

V. Safety Protection

ATMP is acidic and should be avoided from contact with eyes and skin. In case of splashing, rinse immediately with plenty of water.
