Main Application£ºAn agent for complexation, EDTA is mainly used for water treatment, as an additive to ***ergent, a chemical for photography, paper-making and oil-field. It is also used as ***ergent for boiler cleaning and reagent in chemical analysis.
¡¡¡¡¡¡¡¡¡¡¡¡¡¡ 1£® High molecular chemical industry: EDTA is used as polymetization activator for butyl bezene latex, and polyreaction terminator in acrylic fibre production.
¡¡¡¡¡¡¡¡¡¡¡¡¡¡ 2£®Daily chemicals: EDTA is used as additive to ***ergent, skin cream and hair-conditioner.
¡¡¡¡¡¡¡¡¡¡¡¡¡¡ 3£®Paper-making: EDTA is used for treating the steamed fibre. It will promote the whiteness of paper and reduce the incrustation in the steamer.
¡¡¡¡¡¡¡¡¡¡¡¡¡¡ 4£®Pharmaceutical industry: Through cyclopolymerization with methyl amide, EDTA is made into ethyl amide, a remedy for psoriasis. It is also a stablizer for some vaccines and an antihaemoagglutinin.
¡¡¡¡¡¡¡¡¡¡¡¡¡¡ 5£® Textile dyeing and printing: EDTA will promote colour ability of the dyestuff and brightness of the dyed fabric.
