CAS No. 23605-74-5
Aliases: 1, 6-hexylenediamine tetramethylenephosphonic acid, hexylenediamine tetramethylenephosphonic acid, HMDTMP
Molecular formula C10H28N2O12P4
Relative molecular mass: 492.3
Structural formula
Ⅰ. Performance and use
At room temperature, HDTMPA is a white crystalline powder, slightly soluble in water, and its solubility is less than 5% at room temperature.
HDTMPA 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 phosphonic acids, the calcium sulfate scale inhibition performance is the best, not only the scale inhibition rate is high, the effective time is long, so it is especially suitable for oil field extrusion treatment. HDTMPA can also be used in boiler water treatment.
