EDTA-2Na is used in detergent, liquid soap, shampoo, agricultural chemicals, fixer solution for development of colour film, water cleaner, PH modifier. When stating the redox reaction for the polymerization of butyl benzene rubber, it is used as part of activator for the complexation of metal ion and control of polymerization speed.
Application
An agent for chealte, EDTA is mainly used for water treatment, as an additive to detergent, 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 poiduction.
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 imide, a remedy for psoriasis. It is also a stablizer for some vaccines and an antihaemoagglutinin.
5. Textile dyeing and printing: EDTA will promote color ability of the dyestuff and brightness of the dyed fabric.
