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

摘要

: Process for the continuously operated distillation of the solvent used in the synthesis of an oxirane by. reaction of a hydroperoxide with an organic compound, wherein the mixture comprising the solvent which is obtained in the synthesis and subsequent work-up is separated in a dividing wall column into a low-boiling fraction, an intermediate-boiling fraction and a high-boiling fraction and the solvent is taken off as intermediate-boiling fraction from the side offtake of the column
