METHOD FOR PREPARING ORGANIC HYDROPEROXIDE COMPRISING REDUCED AMOUNT OF IMPURITIES Russian patent published in 2006 - IPC C07C407/00 C07D301/19 

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention proposes a method for synthesis of organic hydroperoxide comprising the reduced amount of impurities. Method involves the following steps: (a) oxidation of organic compound to yield the reaction product comprising organic hydroperoxide; (b) contacting at least part of the reaction product comprising organic hydroperoxide with the basic aqueous solution; (c) separation of hydrocarbon phase containing organic hydroperoxide from an aqueous phase; (d) washing out at least part of the separated hydrocarbon phase containing organic hydroperoxide, and (e) contacting at least part of hydrocarbon phase containing organic hydroperoxide with a protective layer comprising a solid adsorbent wherein a solid adsorbent shows porosity 50-98% by volume. Except for, invention proposes a method for preparing oxirane compound from hydrocarbon phase obtained at the step (e) by the method described above and containing alkylaryl hydroperoxide. The presence of the protective layer reduces the pressure increment in the catalyst layer that is caused by the declined content of impurities in the raw comprising alkylaryl hydroperoxide.

EFFECT: improved preparing method.
