HMDTMPA
ThFine
CAS No. 23605-74-5
HexaMethyleneDiamineTetra (MethylenePhosphonic Acid)
CAS No.: 23605-74-5 EINECS No.: 245-781-0
Molecular Formula: C10H28N2O12P4 Molecular Weight: 492.3
RIDADR: UN 3261 8/PG II
Structural Formula:
Properties:
HMDTMPA is 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. But in water treatment industry, HMDTMPA is mainly used as scale inhibitor for calcium sulfate and barium sulfate.
Among all the organic phosphonic acids, HMDTMPA has the best scale inhibition performance for calcium sulfate, and not only the scale inhibition rate is high, the effective time is long, so especially suitable for extrusion treatment in oilfield. HMDTMPA can also be used for water treatment in boilers.
