HMDTMPA Description

HexaMethyleneDiamineTetra (MethylenePhosphonic Acid) HMDTMPA CAS No 23605-74-5 Dequest: 2051 Molecular Formula: C10H28N2O12P4 Molecular Weight: 492.3 Structural Formula: Properties: HMDTMPA is a white crystal powder at room temperature, slightly soluble in water, with solubility less than 5%. HMDTMPA can inhibit most scale formation such as calcium carbonate, calcium sulfate, barium sulfate and ferric oxide. As water treatment chemicals, HMDTMPA is used as scale inhibitors for calcium sulfate and barium sulfate, for calcium sulfate in particular. It has high scale inhibition rate and can last for long effective time. HMDTMPA can be used for crush treatment in oilfield and for water treatment in boiler.
