CAS No 23605-74-5
Equivalent of Dequest: 2051
Molecular Formula: C10H28N2O12P4 Molecular Weight: 492.3
Structural formula: N—(CH2)—NH2O3P—CH2H2O3P—CH2CH2—PO3H2CH2—PO3H26
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, HDTMPA 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.
