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.
