CA 2483447

The present invention relates to a process for the epoxidation of olefins by i) reacting an olefin with hydrogen peroxide in presence of an epoxidation catalyst and an alcoholic solvent; ii) separating product olefin oxide and unreacted olefin from the reaction product of step i); iii) recovering a stream comprising the alcoholic solvent,characterized by iv) subjecting the recovered stream of step iii) to hydrogenation.

L'invention concerne un procédé d'époxydation des oléfines consistant à i) mettre à réagir une oléfine avec du peroxyde d'hydrogène en présence d'un catalyseur d'époxydation et d'un solvant alcoolique; ii) séparer le produit d'oxyde d'oléfine et l'oléfine n'ayant pas réagi du produit réactionnel de l'étape i); iii) récupérer un flux contenant le solvant alcoolique. L'invention est caractérisée en ce que iv) le flux récupéré à l'étape iii) est soumis à l'hydrogénation.
