The invention relates to a method for the production of propylene oxide, comprising the following steps: (a) propene is reacted with hydrogen peroxide in a solvent in the presence of a suitable catalyst in order to obtain a mixture (G0) of propylene oxide, solvent, unreacted propene, unreacted hydrogen peroxide and oxygen, (b) the propylene oxide is separated from the mixture (G0) in such a way that a mixture (G1) of unreacted propene and oxygen is obtained, and (c) the mixture (G1) is used.
L'invention concerne un procédé de fabrication d'oxyde de propylène consistant au moins (a) à transformer du propène avec un peroxyde d'hydrogène dans un solvant en présence d'un catalyseur adapté, avec obtention d'un mélange (G0), le mélange (G0) contenant de l'oxyde de propylène, des solvants, du propène non transformé, du peroxyde d'hydrogène non transformé et de l'oxygène ; (b) à séparer l'oxyde de propylène du mélange (G0) de manière à obtenir un mélange (G1) contenant du propène non transformé et de l'oxygène ; et, (c) à exploiter le mélange (G1).
