CAS No. 6419-19-8
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 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. Because of its high purity, it
can be used in woven & dyeing industries and as metal surface
treatment agent.

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