METHOD FOR OXIDATION OF ALKENE Russian patent published in 2006 - IPC C07D301/12 B01J29/90 

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention proposes a method for oxidation of alkene. Method involves interaction of alkene with hydroperoxide in the presence of aluminum-free titanium-containing zeolite catalyst and the following regeneration of catalyst by a method involving thermal treatment of catalyst in the presence of hydrogen-containing gaseous flow at temperature above 120°C. Proposed method of regeneration of catalyst provides retaining mainly its initial catalytic activity and in using the stationary layer of catalyst the regeneration can be carried out without discharge of catalyst. Identical solvents can be used both for regeneration of catalyst and for carrying out the oxidation reaction and these solvents can be recirculated.

EFFECT: improved method for oxidation.
