Zusammenfassung:A process for the preparation of alkylene oxide, which process involves mixing fresh feed containing organic hydroperoxide and alkene with a recycle stream to obtain a reaction mixture containing of from 5 to 80% wt of alcohol, based on total amount of reaction mixture, contacting the reaction mixture with a heterogeneous epoxidation catalyst to obtain a stream containing alkylene oxide and alcohol, and recycling of from 30 to 95% wt of the stream obtained in step (ii) to step (i).
