| 释义 | 二乙烯三胺五亚甲基膦酸，DETPMP Dequest:2060 。分子式：C9H28O15N3P5， 相对分子质量：573.2 。棕黄色棕红色粘稠液体。可用作过氧化物稳定剂、纺织印染用螯合剂、颜料的分散剂、氧脱木素稳定剂、化肥中微量元素携带剂、混凝土添加剂。此外，在造纸、电镀、金属酸洗和化妆品等方面也得到了广泛应用。还可作氧化性杀菌剂的稳定剂。 一、产品性能DTPMPA无毒，易溶于酸性溶液中，阻垢缓蚀效果俱佳且耐温性好，可抑制碳酸盐、硫酸盐垢的生成，在碱性环境和高温下(210℃以上)阻垢缓蚀性能较其它有机磷好。 二、质量指标符合HG/T 3777-2005 项 目 指 标 外 观 棕黄色棕红色粘稠液体 活性组分% ≥ 50.0 亚磷酸（以PO3计）% ≤ 3.0 氯化物 （以Cl计）% 12 - 17 铁（以Fe计）含量ppm≤ 35 密度（20℃）g/cm 1.35～1.45 PH(1%水溶液) ≤ 2.0 三、应用范围与使用方法DTPMPA在水处理中用作循环冷却水和锅炉水的阻垢缓蚀剂，特别适用于碱性循环冷却水中作为不调pH的阻垢缓蚀剂，并可用于含碳酸钡高的油田注水和冷却水、锅炉水的阻垢缓蚀剂；在复配药剂中单独使用本品，无需投加分散剂，污垢沉积量仍很小。 DTPMPA也可用作过氧化物稳定剂、纺织印染用螯合剂、颜料的分散剂、氧脱木素稳定剂、化肥中微量元素携带剂、混凝土添加剂。此外，在造纸、电镀、金属酸洗和化妆品等方面也得到了广泛应用。还可作氧化性杀菌剂的稳定剂。 四、包装与贮存DTPMPA用塑料桶包装，每桶25Kg或根据用户需要确定。贮于室内阴凉处，贮存期为十个月。 五、安全防护DTPMPA为酸性，应避免与眼睛、皮肤接触，一旦溅到身上，应立即用大量水冲洗。 -------------------------------------------------------------------------------- Diethylene Triamine Penta (Methylene Phosphonic Acid) (DTPMPA) CAS No 15827-60-8 Dequest: 2060 Molecular Formula: C9H28O15N3P5Molecular 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: items index Appearance Brown transparent liquid Active acid % 48.0-52.0 Phosphorous acid（as PO3）% 3.0 max Chloride (as Cl)% 12-17 Density （20℃）g/cm 1.35-1.45 pH（1% solution） 2.0 Fe ppm 35 maxUsage: DTPMPA can be used as scale and corrosion inhibitor in circulating cool water system and boiler water, and especially in alkali circulating cool water system without additional pH regulation, It can also be used in oilfield refill water, cool water and boiler water with high concentration of barium carbonate. When used alone, little scale sediment is found even none of dispersant is used. DTPMPA can also be used as peroxide stabilizer, chelating agent in woven & dyeing industry, pigment dispersant, microelement’s carrying agent in fertilizer and concrete modifier. In addition, DTPMPA is used in papermaking, electroplating, acid cleaning and cosmetics. Package and Storage: Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place. Safety Protection: Acidity, Avoid contact with eye and skin, once contacted, flush with water.
