Molecular Formula:
N(CH2PO3H2)3
Molecular weight: 299.05
Structural Formula:
Properties:
Tris(Methylene Phosphonic Acid) Amine
has excellent chelation, low threshold inhibition and
lattice distortion ability. It can prevent scale formation,
calcium carbonate in particular, in water system.
Tris(Methylene Phosphonic Acid) Amine
has good chemical stability and is hard to be hydrolyzed in
water system. At high concentration, it has good corrosion
inhibition.
Tris(Methylene Phosphonic Acid) Amine
is used in industrial circulating cool water system and
oilfield water pipeline in fields of thermal power plant and
oil refinery plant. Tris(Methylene
Phosphonic Acid) Amine can decrease scale formation and
inhibit corrosion of metal equipment and pipeline.
Tris(Methylene Phosphonic Acid) Amine
can be used as chelating agent in woven and dyeing
industries and as metal surface treatment agent.
The solid state of
Tris(Methylene Phosphonic Acid) Amine
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.
