Abstract

The present invention pertains to a process for separating monochloroacetic acid and dichloroacetic acid from one another via extractive distillation, comprising the steps of (i) contacting a mixture comprising monochloroacetic acid and dichloroacetic acid with an extractive agent which is chemically stable and which hasa BF3 affinity of between 65 kJ/mole and 110 kJ/mole, (ii) distilling the mixture to obtain a monochloroacetic acid stream and a stream comprising dichloroacetic acid and the extractive agent, and (iii) regenerating the extractive agent.
