CAS No. 6419-19-8
Molecular Formula:
N(CH2PO3H2)3
Molecular weight: 299.05
Structural Formula:
Properties:
ATMPA has excellent chelation,
low threshold inhibition and lattice distortion ability. It
can prevent scale formation, calcium carbonate in
particular, in water system.
ATMPA
has good chemical stability and is hard to be hydrolyzed in
water system. At high concentration, it has good corrosion
inhibition.
ATMPA is used in industrial
circulating cool water system and oilfield water pipeline in
fields of thermal power plant and oil refinery plant.
ATMPA can decrease scale formation and inhibit corrosion
of metal equipment and pipeline.
ATMPA can be used as chelating
agent in woven and dyeing industries and as metal surface
treatment agent.
The solid state of
ATMPA
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:
ATMPA is usually used together
with organophosphoric acid, polycarboxylic acid and salt to
built all organic alkaline water treatment agent.
ATMPA 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.
