摘要

Continuous process for between the separation of the in the case of the oxirane synthesis by reacting a hydroperoxide with an organic compound resulting oxirane has been completed, characterized in that the in the synthesis product mixture obtained in a dividing wall column in a slightly -, means - and high-boiling fraction separated and the oxirane medium boiler fraction on the sides of the trigger point of the column and the hydroperoxide from the high-boiling fraction with the bottom of the column is removed from.
