Amino Tri(Methylene Phosphonic Acid)
ThFine
CAS No. 6419-19-8
Amino Tri(Methylene Phosphonic Acid)
CAS No.: 6419-19-8 EINECS No.: 229-146-5
Molecular Formula: N(CH2PO3H2)3 Molecular Weight: 299.05
RIDADR: UN 3265 8/PG III
Structural Formula:
Properties:
Amino Tri(Methylene Phosphonic Acid) has good chelating, low limit inhibition and lattice distortion ability. It can prevent the formation of scale salts in water, especially the formation of calcium carbonate scale. Amino Tri(Methylene Phosphonic Acid) has good chemical stability and is hard to be hydrolyzed in water. When the water concentration is high, it shows a good corrosion inhibition effect.
Amino Tri(Methylene Phosphonic Acid) is used in circulating cooling water of thermal power plants and oil refineries, also in oil field water injection system, to play a role in reducing the corrosion and scaling of metal equipment or piping. Amino Tri(Methylene Phosphonic Acid) is used as metal ion chelating agent or metal surface treatment agent in the textile printing and dyeing industry.
The solid state of Amino Tri(Methylene Phosphonic Acid) is crystalline powder, easily soluble in water, easy to absorb moisture, and easy to be transport and used, especially suitable for cold winter areas.
