Hexamethylene Diamine Tetra (Methylene Phosphonic Acid) (HDTMPA)
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.
Scope of application and use of methods  
It is mainly used in water treatment to inhibit calcium sulfate and barium sulfate scale, heavy metal ion chelating agent and sludge conditioning agent; titanium dioxide, kaolin, or drilling mud dispersants; industrial cleaning agent in the chelating agents.

Because this product is insoluble in water, it should be react with base chemicals to form water soluble salt before use in water treatment process. Commonly an ammonium salt or sodium salt are used by reaction of the product and sodium hydroxide or ammonium hydroxide and then neutralized by phosphoric acid.
