摘要： 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 has a 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.

摘要： The invention relates to a process wherein a stream comprising dichlorohydrin, water, and HCI is separated into a stream which is rich in dichlorohydrin and low in HCI and an aqueous HCI stream which is low in dichlorohydrin. The process involves the distillation of the mixture comprising dichlorohydrin, water, and HCI with an amount of water being added before and/or during the distillation such that the water concentration during the distillation is on the line D-E, or to the right thereof, in the phase diagram of FIG. 1.
