The present invention relates to a process for the working up of a product stream from the epoxidation of olefins that contains olefin, olefin oxide, water-miscible organic solvent and water, by separating this product stream into an overhead product containing olefin, olefin oxide and organic solvent, and into a bottom product containing organic solvent and water, wherein the separation takes place in a pre-evaporator with at most 5 theoretical separation stages, and 20 to 60% of the total amount of organic solvent introduced with the product stream is removed with the overhead product and the residue remains in the bottom product, as well as a process for the epoxidation of olefins that includes this working up stage.

L'invention concerne un procédé de fabrication d'un flux de produit léger, à partir de l'époxydation d'oléfines qui contient de l'oléfine, de l'oxyde d'oléfine, un solvant organique miscible dans l'eau et de l'eau, en séparant ce flux de produit léger en un distillat de tête contenant de l'oléfine, de l'oxyde d'oléfine et un solvant organique solvant, et un résidu contenant un solvant organique et de l'eau, dans lequel la séparation a lieu dans un pré-évaporateur avec au moins 5 étapes de séparation théoriques, et entre 20 et 60 % de la quantité totale de solvant organique introduite par le distillat de tête et le résidu reste dans le résidu, ainsi qu'un procédé d'époxydation d'oléfines comportant cette étape de fabrication.
