Process for separating off enol ethers from reaction mixtures containing alcohols

摘要

The invention relates to a gentle process for the separation of enol ethers from mixtures containing water-soluble alcohols by extraction, wherein an aqueous solution of a base is used as the extraction agent in a phase ratio of the amounts of the aqueous phase: enol ether/alcohol mixture of at least 0.5:1 and the extraction is carried out in several stages or continuously with a theoretical number of stages of at least two. The process is particularly suitable for separating off enol ethers which readily decompose during distillation.
