Amino Trimethylene Phosphonic Acid (ATMP) cas no 6419-19-8

Other Names: Amino trimethylene phosphonic acid, Nitrilotrimethylene Triphosphonic Acid, ATMPA, [nitrilotris(methylene)]tri-, potassium salt
Molecular Formula: N(CH2PO3H2)3
Molecular Weight: 299.05

Properties:
ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. It can prevent scale formation, calcium carbonate in particular, in water system.diethylenetriamine penta methylene phosphonic acid ATMP 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. ATMP can decrease scale formation and inhibit corrosion of metal equipment and pipeline. ATMP can be used as chelating agent in woven and dyeing industries and as metal surface treatment agent.
The solid state of ATMP is crystal powder, soluble in water, easily deliquescence, suitable for usage in winter and freezing districts.

Usage:
ATMP is usually used together with organophosphoric acid, polycarboxylic acid and salt to build all organic alkaline water treatment agent. ATMP can be used circulating cool water system for different water quality. The dosage of 1-20mg/L is recommended. As corrosion inhibitor, the dosage of 20-60mg/L is preferred.
