Process for the epoxidation of olefins

Abstract

A process for the catalytic epoxidation of olefins in at least one reaction stage comprising: (a) reacting the olefin with hydrogen peroxide in an organic, water-miscible solvent in the presence of a titanium silicalite catalyst in a reactor while continuously feeding an inert gas stream into the reactor, (b) continuously removing an exit gas stream containing olefin oxide, unreacted olefin, oxygen and inert gas from the reactor, (c) bringing the exit gas stream into contact in an absorption unit with the same solvent as used in the reaction stage, (d) removing a solvent stream loaded with olefin and olefin oxide from the absorption unit and (e) discharging an gas stream containing oxygen and the inert gas from the absorption unit.
