HDTMPA
HDTMPA
HDTMPA能抑制各種水垢（如碳酸鈣垢、硫酸鈣垢、硫酸鋇垢和氧化鐵垢等）的生成，但在水處理中主要用來阻抑硫酸鈣和硫酸鋇垢。在各種有機磷酸中，其阻硫酸鈣垢的性能最好，不僅阻垢率高，有效時間長，因此特別適用於油田的擠壓處理中。HDTMPA也可用於鍋爐水處理中。

CAS No. 23605-74-5 Molecular Formula: C10H28N2O12P4 Molecular Weight: 492.3 Structural Formula:
HMDTMPA is a white crystal powder at room temperature, slightly soluble in water, with solubility less than 5%. HMDTMPA can inhibit most scale formation such as calcium carbonate, calcium sulfate, barium sulfate and ferric oxide. As water treatment chemicals, HMDTMPA is used as scale inhibitors for calcium sulfate and barium sulfate, for calcium sulfate in particular. It has high scale inhibition rate and can last for long effective time. HMDTMPA can be used for crush treatment in oilfield and for water treatment in boiler.
