Application Method:
An agent for complexation, EDTA is mainly used for water treatment, as an additive to detergent, a chemical for photography, paper-making and oil-field. It is also used as detergent 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 detergent, 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.
