DESCRIPTION AND APPLICATIONS

Monochloroacetic acid, chlorinated simplest carboxylic acid, has electron-withdrawing atom (alpha-chlorine) on the next carbon to acid. Alpha-chlorine makes monochloroacetic acid more acidic than acetic acid. It is used as one of the first choice chemical intermediates for the production of;

  • Carboxy Methyl Cellulose and Starch
  • Phenoxyacetic Acid
  • Thioglycolic Acid
  • Cyanoacetic Acid / Malonates / Barbituric Acid
  • Caffeine, Betaine, Vitamin B and pharmaceuticals
  • Glycine
  • Surfactants
  • Indigo dyes
  • Herbicides

The production and use of 1,1,1-trichloroethane and carbon tetrachloride have been phased out throughout the world because of suspected harm to the earth's ozone layer.
