Matumizi:
HEDP inatumika kama kiwango na kizuizi cha kutu katika kuzunguka mfumo wa maji baridi, uwanja wa mafuta na boilers zenye shinikizo la chini katika uwanja kama vile nguvu ya umeme, tasnia ya kemikali, madini, mbolea, nk .. Katika tasnia nyepesi iliyosokotwa, HEDP inatumika kama sabuni ya chuma na isiyo ya kawaida. Katika tasnia ya utengenezaji, HEDP inatumika kama utulivu wa peroksidi na wakala wa kurekebisha rangi; Katika elektroni zisizo za cyanide, HEDP inatumika kama wakala wa chelating. Kipimo cha 1-10mg/L kinapendelea kama kizuizi cha kiwango, 10-50mg/L kama kizuizi cha kutu, na 1000-2000mg/L kama sabuni. Kawaida, HEDP inatumika pamoja na asidi ya polycarboxylic.
