METHOD FOR LIQUID-PHASE OXIDATION OF ETHYLBENZENE TO ETHYLBENZENE HYDROPEROXIDE Russian patent published in 2012 - IPC C07C409/08 C07C407/00 C07D301/19 C07C15/46 

Abstract RU 2464260 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method for liquid-phase oxidation of ethylbenzene to ethylbenzene hydroperoxide, where concentration of ethylbenzene hydroperoxide is kept below 20 wt % with respect to total weight of the reaction mixture and where styrene and/or a styrene derivative is added to ethylbenzene. Concentration of said styrene and/or styrene derivative can range from 0.01 to 5.0 wt %. The styrene derivative is a styrene derivative in which one or more unsubstituted carbon atoms of the styrene have an alkyl group and/or a halogen atom as a substitute. The invention also relates to a method of producing an alkylene oxide, preferably styrene and propyelene oxide.

EFFECT: improved method.
