    摘要： A process for preparing propylene oxide comprises at least the following steps: (a) propene is reacted with a hydroperoxide in a solvent in the presence of a zeolite catalyst to give a mixture (M0), where the mixture (M0) comprises propylene oxide, solvent, unreacted propene, unreacted hydroperoxide and oxygen, (b) the propylene oxide is separated from the mixture (M0) so as to give a mixture (M1) which comprises unreacted propene and oxygen, (c) the mixture (M1) is brought into contact with a liquid medium comprising at least a solvent to give the mixtures (M2) and (M3), where the mixture (M3) comprises part of the unreacted propene and oxygen and the mixture (M2) comprises solvent and residual propene, and  the mixture (M3) which has been separated off and comprises unreacted propene and oxygen has a ratio of oxygen to propene such that the mixture (M3) is not ignitable, and  the mixture (M2) is fed to at least one reaction of propene with hydroperoxide.

    摘要： An organic compound having at least one C—C double bond is epoxidized by means of hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent, wherein a product mixture comprising α-hydroperoxyalcohols is reduced using at least one reducing agent. The process advantageously comprises at least the following steps: (i) reacting an organic compound having at least one C—C double bond with hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent to give a product mixture P1 comprising α-hydroperoxyalcohols; (ii) separating an epoxide formed in the reaction in step (i) and the unreacted organic compound having at least one C—C double bond from P1 or P1′ to give a product mixture P2 or P2′, where P2 comprises the α-hydroperoxyalcohols formed as by-product in the reaction in step (i) and P2′ is largely free of α-hydroperoxyalcohols; (iii) treating P1 and/or P2 with at least one reducing agent so that the α-hydroperoxyalcohols are converted into corresponding glycols to give a product mixture P1′ or P3.
