Abstract

The present disclosure relates to a process for epoxidizing an olefin mixture (11), comprising at least two olefins selected from the group consisting of ethylene, propylene and 1-butylene. Particularly the present disclosure relates to a process comprising contacting the olefin mixture (11) and solvent with hydrogen peroxide (12) in the presence of a heterogeneous Lewis acid catalyst in a reactor; and recovering a product mixture (15) corresponding to the provided olefin mixture (11). The present disclosure further concerns the product obtained by the method as well as the use of the recovered product mixture in the production of polycarbonates, cyclic carbonates and/or polyols, preferably polycarbonate or polyether polyols for use in polyurethane products. The present disclosure also relates to an integrated process for producing epoxides, wherein the olefin mixture is separated from Fischer-Tropsch synthesis (7).
