At room temperature HDTMPA is white crystalline powder, slightly soluble in water. its solubility at room temperature is less than 5%. HDTMPA can inhibit a variety of scale (such as calcium carbonate, calcium sulfate, barium sulfate and iron oxide scale, etc.). It is mainly used in water treatment to prevent and suppress barium sulfate scale. In a variety of organic phosphine, its performance of resisting calcium sulfate scale is of the best. It can effectively inhibit the scale for long time. Therefore it is particularly suitable for use in oilfield water treatment and boiler water treatment. |
