Properties：
White powder, slightly soluble in water, with a solubility in water of less than 5% at room temperature. It can form water-soluble salts with strong bases and has strong hydrolysis resistance.
Applications:
HDTMPA can inhibit the formation of various types of scale (such as calcium carbonate scale, calcium sulfate scale, barium sulfate scale, and iron oxide scale, etc.), but in water treatment, it is mainly used to inhibit calcium sulfate and barium sulfate scales. Among various organic phosphonic acids, it has the best performance in inhibiting calcium sulfate scale, featuring not only a high scale inhibition rate but also a long effective duration, thus being particularly suitable for squeeze treatment in oil fields. HDTMPA can also be used in boiler water treatment.v
