Amino Trimethylene Phosphonic Acid (ATMP)


CAS No. 
6419-19-8
Molecular Formula: 
N(CH2PO3H2)3   
Molecular weight:
299.05
Structural Formula:


Properties:
ATMP has excellent chelation, low threshold inhibition, and lattice distortion ability. It can prevent scale formation, calcium carbonate, in particular, in the water system. ATMP has good chemical stability and is hard to be hydrolyzed in a water system. At high concentrations, it has good corrosion inhibition.
ATMP is used in industrial circulating cool water system and oilfield water pipeline in thermal power plant and oil refinery plant fields. ATMP can decrease scale formation and inhibit the corrosion of metal equipment and pipeline. ATMP can be used as a chelating agent in woven and dyeing industries and as a 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. Its high purity can be used in woven & dyeing industries and as a metal surface treatment agent.
