Organophosphoric Antiscale and Corrosion Inhibitors, Chelant

Amino Trimethylene Phosphonic Acid
(ATMP)

CAS No.  6419-19-8

Molecular Formula: N(CH2PO3H2)3

Molecular weight: 299.05

Structural Formula:

Amino Trimethylene Phosphonic Acid (ATMP) Structural Formula

Properties:

Amino Trimethylene Phosphonic Acid has excellent chelation, low threshold inhibition and lattice distortion ability. ATMP can prevent scale formation, calcium carbonate in particular, in water system. Amino Trimethylene Phosphonic Acid has good chemical stability and is hard to be hydrolyzed in water system. At high concentration, ATMPA has good corrosion inhibition.

ATMP is used in industrial circulating cool water system of thermal power plant and oil refinery plant. ATMP can decrease scale formation and inhibit corrosion of metal equipment and pipeline. ATMPA can be used as chelating agent in woven and dyeing industries and as metal surface treatment agent.

The solid state of Amino Trimethylene Phosphonic Acid is crystal powder, soluble in water, easily deliquescence, suitable for usage in winter and freezing districts. Because of its high purity, ATMPA can be used in woven & dyeing industries and as metal surface treatment agent.
