Abstract:
A method has been disclosed of obtaining high purity, colourless monochloroacetic acid encompassing the chlorination of acetic acid with chlorine in the presence of a catalyst, followed by the recovery of the catalyst through vacuum distillation and purification of the obtained liquid raw product by its hydrodehalogenation by hydrogen in the presence of a palladium catalyst and then vacuum distillation.

Claim (Index 1):
The method of obtaining high purity, colourless monochloroacetic acid encompassing the chlorination of acetic acid with chlorine in the presence of a catalyst, followed by the recovery of the catalyst through vacuum distillation and purification of the remaining liquid raw product by its hydrodehalogenation in the presence of a palladium catalyst and then vacuum distillation, characterised in that\n a. hydrolysis is conducted of anhydrides and acid chlorides which are present in the stream of the liquid product obtained after the stage of recovery of the catalyst, whereby hydrolysis is conducted with such a continuous excess of water with respect to the content of chlorides and anhydrides that the concentration of water in the mixture leaving to the next stage is between 0.05 and 5% by weight, in a temperature of between from 50 to 160\u00b0 C. and then b. the excess water is removed by a reaction with acid chlorides so that the concentration of water in the reaction mixture entering the hydrodehalogenation process is less than 2%.
