CAS No. 6419-19-8 Molecular Formula: N(CH2PO3H2)3 Molecular weight: 299.05 ATMP is used in industrial circulating cool water system and oilfield water pipeline in fields of thermal power plant and oil refinery plant. ATMP can decrease scale formation and inhibit corrosion of metal equipment and pipeline. ATMP can be used as chelating agent in woven and dyeing industries and as metal surface treatment agent. The solid state of ATMP is crystal powder, soluble in water,[...]

CAS No. 15827-60-8 Molecular Formula: C9H28O15N3P5 Molecular weight: 573.2 Properties: DTPMPA is innocuous, easy to be dissolved in acid solution. DTPMPA has excellent scale and corrosion inhibition and good thermal tolerance ability. DTPMPA can inhibit the scale formation of carbonate, sulfate and phosphate. On situation of alkali environment and high temperature (above 210℃) DTPMPA has better scale and corrosion inhibition effect than other organophosphines. Specification: Appearance:[...]
