Project Description
HexaMethyleneDiamineTetra (MethylenePhosphonic Acid) HMDTMPA
Synonyms: HDTMP; HDTMPA; HDTMP(A)
CAS No.: 23605-74-5
Molecular Formula: C10H28N2O12P4
Molecular Weight: 492.3
Structural Formula:
Properties:
HMDTMPA is a white crystal powder at room temperature, slightly soluble in water (solubility less than 5%).
HexaMethyleneDiamineTetra (methylene phosphonic Acid) is featured by its high inhibition degree and sustaining effect. HMDTMPA is a multifunctional antiscalant with excellent effect to CaCO3, CaSO4, BaSO4, and FeO. Especially in inhibiting CaSO4scale.
It has a high scale inhibition rate and can last for a long effective time. HMDTMPA can be used for crush treatment in the oilfield and for water treatment in a boiler. However, its chelating ability is comparatively weak. HexaMethyleneDiamineTetra (methylene phosphonic Acid) is particularly suitable for the conditions with desirable free metal ions.
