Specification of Amino Trimethylene Phosphonic Acid (ATMP)
Product
Furfural Alcohol
CAS NO.
6419-19-8
Formula
N(CH2PO3H2)3
Mol Wt.
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. 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.
