FIELD: chemistry.
SUBSTANCE: invention refers to method of alkylen oxide production as involving (i) mixing the original raw stock containing organic hydroperoxide and alken with and recycled flow to prepare the reaction mixture containing alcohol 5 to 80 wt % per total amount of the reaction mixture; (ii) contacting the reaction mix and the heterogeneous epoxidation catalyst to make the flow containing alkylen oxide and alcohol; and (iii) recycling the flow 30 to 95 wt % from the stage (ii) to the stage (i).
EFFECT: method improvement.
