ATMP
| CAS No.: 6419-19-8 | Molecular Formula: N(CH2PO3H2)3 |
|
Synonyms: |
Nitrilotrimethanephosphonic Acid, Dequest 2000 Nitrilotrismethylenetriphosphonic Acid |
Molecular Weight: 299.05 |
Properties:
ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. It prevents scale formation, calcium carbonate in particular, in water system. It shows good chemical stability and is hard to be hydrolyzed in water system. Solid 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 built all organic alkaline water treatment agent.
ATMP is used in many different circulating cool water system and oilfield water pipeline in fields of thermal power plant and oil refinery plant. ATMP can be used as chelating/sequestering agent in woven and dyeing industries and as metal surface treatment agent.
Because of its high purity of the solid ATMP, it is used in woven & dyeing industries and as metal surface treatment agent.
