CAS No. 6419-19-8 EC No. 229-146-5 Dequest: 2000
Molecular Formula: N(CH2PO3H2)3 Molecular weight: 299.05
Structural Formula:
Properties:
ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. It can prevent scale formation, especially calcium carbonate in water system.
ATMP has good chemical stability and is hard to be hydrolyzed in water system. At high concentration, ATMP has good corrosion inhibition.
ATMP is widely used in industrial cooling water systems of thermal power plants and oil refinery plants, as well as oilfield water refill systems. ATMP can decrease scale formation and inhibit corrosion of metal equipment and pipeline.
ATMP can be used as chelating agent in textiles dyeing printing industries, it is also used as metal surface treatment agent.
Solid ATMP is crystal powder, soluble in water, easily deliquescence, suitable for usage in winter and freezing districts. Because of its high purity, it can be used in textile dyeing printing industries and used as metal surface treatment agent.
