Liquid phase oxidation of C6-C8 cycloolefins with air oxygen catalyzed by metal-containing microstructured carbon materials

Abstract

Catalytic oxidation of cyclohexene and its methyl and vinyl derivatives with air oxygen in the presence of Co- and Mo-Co-modified microstructured carbon materials has been studied. Regardless of structure of the parent cycloalkene, cobalt-containing samples at 40–50°C are highly selective towards formation of corresponding hydroperoxides, whereas molybdenum-cobalt containing samples are selective towards cycloalkenes epoxidation. The ratio of epoxide to unsaturated alcohol strongly depends on the structure of the starting substrate.
