Applications
As 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.
