Abstract (en)
[origin: WO2004009569A1] 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 high-boiling fraction and the oxirane is taken off with the middle-boiling fraction 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.
