Amino Trimethylene Phosphonic Acid ( ATMP Solid ) [CAS No.] 6419-19-8 Dequest: 2000 Molecular Formula: N(CH2PO3H2)3 Molecular weight: 206 Properties: This product is white crystal powder, soluble in water, prone to absorption of moisture, good thermal stability, has good antiscale performance for calcium carbonate below 200℃. It can chlelate with such ions as Fe, Cu, Al and Zn to form stable complex. This product is in solid shape, suitable for transport and usage, especially for frigid situation. This product is widely used in industrial circulating cool water system and oilfiled water pipeline, it can decrease scale formation and inhibit corrosion of metal equipment and pipeline. Because of its high pure grade, it can be used as chelating agent in weave and dyeing industries and as metal surface treatment agent. Specification: (ATMP) Appearance White crystal powder Active component % ≥ 95.0 Active component (ATMP)% ≥ 80.0 Phosphoric acid (asPO43 )% ≤ 1.0 Chloride (as Cl-)% ≤ 2.0 pH value(1% water solution) ≤ 2.0 Fe ion (Fe) ppm ≤ 20 Usage: This product is usually used together with organophosphoric acid, copolymer and zinc salt to built full organic alkaline water treatment agent, it can be used in many different circulating cool water system. The dosage of 1-10ppm is recommended, while the dosage of 20-60mg/L is preferred as corrosion inhibitor.
