HDTMP
Alternative name:hexanediamine tetramethylene phosphonic acid; 1,6-hexanediamine tetramethylidene phosphonic acid
CAS No.: 23605-74-5
Molecular formula:C10H28N2O12P4
HDTMP can inhibit the formation of various scale, such as calcium carbonate scale, calcium sulfate scale, barium sulfate scale and iron oxide scale, but it is mainly used to inhibit calcium sulfate and barium sulfate scale in water treatment. Among all kinds of organic phosphoric acid, the performance of calcium sulfate scale inhibition is the best. It has high scale inhibition rate and long effective time, so it is especially suitable for extrusion treatment in oil field. Hdtmpa can also be used in boiler water treatment.
