Uses: HDTMPA is a white crystalline powder at room temperature, slightly soluble in water, and its solubility is 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 organic phosphoric acids, it has the best performance in inhibiting calcium sulfate scale, not only has high scale inhibition rate, but also has a long effective time, so it is especially suitable for extrusion treatment in oil fields. HDTMPA can also be used in boiler water treatment. Mainly used to synthesize organosilicon compounds
