摘要： The present invention relates to a liquid phase process for preparing an olefin oxide from an olefin in a cascade of two or more reactors, in a baffled tank reactor or in a plug flow reactor which process comprises the steps of a) contacting the olefin in a solvent with oxygen or an oxygen-containing gas in a first reactor of the reactor cascade or in a first stage of the baffled tank reactor or of the plug flow reactor, thereby producing a mixture comprising olefin oxide, non-converted olefin, solvent and by-products and b) transferring at least a portion of the mixture obtained in step a) to a second reactor of the reactor cascade or to a second stage of the baffled tank reactor or plug flow reactor, adding an additional amount of i) oxygen or an oxygen-containing gas and/or ii) olefin to the mixture and continuing the reaction.
