Abstract: The invention relates to a continuously operated process for the purification by distillation of the oxirane formed in the oxirane synthesis by reaction of a hydroperoxide with an organic compound, wherein the crude oxirane is separated in a dividing wall column into low-, intermediate- and high-boiling fractions and the oxirane is taken off as intermediate boiler at the side offtake in a concentration of at least 99.9%.

Abstract: Continuously operated process for the intermediate isolation of the oxirane formed by reaction of a hydroperoxide with an organic compound in the oxirane synthesis, wherein the product mixture formed in the synthesis is fractionated in a dividing wall column to give a low-boiling fraction, an intermediate-boiling fraction and a high-boiling fraction and the oxirane is taken off in the intermediate-boiling fraction at the side offtake and the hydroperoxide is taken off in the high-boiling fraction at the bottom of the column.

Abstract: The invention relates to a method for the epoxidation of an organic compound comprising at least one C-C double bond, using hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent. Said method is characterised in that a product mixture containing .alpha.-hydroperoxy alcohols is reduced using at least one reductant. The invention also relates to a method for the epoxidation of an organic compoun d comprising at least one C-C double bond, using hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent, characterised in that said method comprises at least the following steps: (i) an organic compound comprising at least one C-C double bond is reacted with hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent to obtain a product mixture P1 containing .alpha.-hydroperoxy alcohols; (ii) an epoxide that has been obtained by the reaction in step (i) is separated from P1 or P1', together with the non-converted organic compound comprising at least one C-C double bond, to obtain a product mixture P2 or P2', P2 containing the .alpha.- hydroperoxy alcohols that have occurred as by-products in the reaction in st ep (i) and P2' being substantially devoid of .alpha.-hydroperoxy alcohols. (iii ) at least one reductant is added to P1 and/or P2, whereby the .alpha.- hydroperoxy alcohols are converted into corresponding glycols, obtained in a product mixture P1' or P3.

Abstract: A process for the preparation of an epoxide in the presence of a zeolite catalyst, in which (i) an alkene is reacted with a hydroperoxide in the presence of the catalyst to obtain the epoxide, at least one alkali metal salt being fed into the reaction in at least one precursor stream, wherein (ii) during the reaction the addition of the at least one alkali metal salt is stopped and hydroperoxide and alkene are still fed into the reaction.

Abstract: The invention relates to a method for the production of propylene oxide, whereby (i) propylene is reacted with hydrogen peroxide in the presence of methanol to form propylene oxide, resulting in a mixture (Gi), comprising propylene oxide, methanol, water and unreacted hydrogen peroxide, (ii) from mixture (Gi) a mixture (Gii), comprising methanol, water and hydrogen peroxide is separated off, yielding a mixture (Ga), comprising propylene oxide. Water is separated off from mixture (Gii) to give a mixture (Giii), comprising methanol and methyl formate.
