PROCESS FOR THE CONTINUOUSLY OPERATED INTERMEDIATE ISOLATIONOF THE OXIRANE FORMED IN THE COPRODUCT-FREE OXIRANE SYNTHESIS BY MEANS OF ADIVIDING WALL COLUMN

摘要

The invention relates to a continuous method for the intermediate separation of the oxirane produced by the reaction of a hydroperoxide with an organic compound, characterised in that the product mixture generated during the synthesis is separated in a partition-wall column into a low-, middle and hi gh- boiling fraction and the oxirane is taken off with the middle-boiling fracti on at the side tap point of the column and the hydroperoxide is taken off with the high-boiling fraction from the bottom of the column.
