Product Description

Amino Trimethylene Phosphonic Acid


CAS No. 6419-19-8

Molecular Formula: N(CH2PO3H2)3

Molecular weight: 299.05

Synonyms:Nitrilo trimethane phosphonic acid, Dequest 2000

Structural Formula:


ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. It can prevent scale formation,

calcium carbonate in particular, in water system. It has good chemical stability and is hard to be hydrolyzed in

water system. At high concentration, it has good corrosion inhibition.

ATMP is used in industrial circulating cool water system and oilfield water pipeline in fields of thermal power plant

and oil refinery plant. It can decrease scale formation and inhibit corrosion of metal equipment and pipeline. It can

be used as chelating agent in woven and dyeing industries and as metal surface treatment agent.

Solid ATMP is crystal powder, soluble in water, easily deliquescence, suitable for usage in winter and freezing

districts. Due to its high purity, it can be used in woven dyeing industries and as metal surface treatment agent.
