ATMP

タイトルまたは説明

CAS No. ********8 Molecular Formula: N(CH2PO3H2)3 Molecular weight: **9.*5 Synonyms: Nitrilotrimethanephosphonic acid, Dequest ***0 Structural Formula: Properties: ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. It can prevent scale formation, calcium carbonate in particular, in water system. It 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. It can decrease scale formation and inhibit corrosion of metal equipment and pipeline. It can be used as chelating agent in woven and dyeing industries and as metal surface treatment agent. Solid ATMP is crystal powder, soluble in water, easily deliquescence, suitable for usage in winter and freezing districts. Due to its high purity, it can be used in woven & dyeing industries and as metal surface treatment agent.
