Structural Formula:

1· Performance and Applications

HDTMPA is white crystalline powder at room temperature, slightly soluble in water, with a solubility of less than 5% at room temperature.

HDTMPA can inhibit the formation of various scales (such as calcium carbonate scale, calcium sulfate scale, barium sulfate scale and iron oxide scale, etc.), but it is mainly used to inhibit calcium sulfate and barium sulfate scale in water treatment. Among various organophosphonic acids, it has outstanding performance in inhibiting calcium sulfate scale, with not only high scale inhibition rate but also long effective time, so it is especially suitable for squeeze treatment in oil fields. HDTMPA can also be used in boiler water treatment.
