Other Names: Amino trimethylene phosphonic acid, Nitrilotrimethylene
Triphosphonic Acid, ATMPA, [nitrilotris(methylene)]tri-, potassium salt
Molecular Formula: N(CH2PO3H2)3
Molecular Weight: 299.05
Properties:
ATMP
has excellent chelation, low threshold inhibition and lattice
distortion ability. It can prevent scale formation, calcium carbonate in
particular, in water system.
diethylenetriamine penta methylene phosphonic acid
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.
Usage:
ATMP is
usually used together with organophosphoric acid, polycarboxylic acid
and salt to build all organic alkaline water treatment agent. ATMP can
be used circulating cool water system for different water quality. The
dosage of 1-20mg/L is recommended. As corrosion inhibitor, the dosage of
20-60mg/L is preferred.
