Abstract: The invention relates to a continuous method for the epoxidation of olefins with hydroperoxide, characterised in that epoxidation is carried out in a reactor which contains at least one catalyst suspended in a liquid phase. Th e catalyst is guided through a device which is incorporated into the reactor a nd which comprises openings and channels. The invention is also characterised i n that the catalyst is retained in a reaction system by means of transversal filtration during the separation of the liquid-containing epoxide.

Abstract: Process for the continuously operated purification by distillation of the methanol used as solvent in the synthesis of propylene oxide by reaction of a hydroperoxide with propylene, with the methoxypropanols being separated off simultaneously, wherein the solvent mixture obtained in the synthesis is separated in a dividing wall column into a low-boiling fraction including methanol, an intermediate-boiling fraction containing the methoxypropanols as azeotrope with water and a high-boiling fraction including water and propylene glycol.

Abstract: 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.
