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