PROCESS FOR THE CONTINUOUSLY OPERATED DISTILLATION OF THE SOLVENT USED IN A COPRODUCT-FREE OXIRANE SYNTHESIS

摘要

The invention relates to a method for the continuous distillation of thesolvent used in oxirane synthesis by reaction of a hydroperoxide with anorganic compound, characterised in that the mixture arising after thesynthesis and subsequent working up, which comprises the solvent, is separatedin a partition-wall column into a low-, middle- and high-boiling fraction andthe solvent drawn off as middle-boiling fraction from the side tap of thecolumn.
