Synonyms: BHMTPMPA; BHMT; Bis(HexaMethylene Triamine Penta (Methylene Phosphonic Acid)); Dequest 2090; Gyptron KT-252; Mayoquest 1900
CAS No.: 34690-00-1
Molecular Formula: C17H44O15N3P5
Molecular Weight: 685
BHMTPMPA is a high-efficient chelating scale inhibitor, it has a good effect to carbonate and sulfate scale. BHMTPMPA has good water-soluble properties and heat tolerance. Bis(Hexamethylene Triamine Penta (Methylene Phosphonic Acid) has high calcium ion tolerance in a wide pH ranges and temperature as high as 120℃.
BHMTPMPA has a good effect on inhibiting scale by chelation, especially to carbonate and sulfate scale. It can enhance the concentration ration in circulating water and reduce the consumption rate. Combined with ATMP and HEDP, BHMTPMPA has lower total phosphorus content and higher molecular weight.
