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, calcium carbonate in particular, in water system. 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 e
quipment 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. Because of its high purity, it can be used in woven & dyeing industries and as metal surface
treatment agent.
