Abstract
An improved process for preparing alkanones and alkanols by oxidizing an alkane and/or alkene having from 3 to 30 carbon atoms to form an oxidation mixture containing alkylhydroperoxide. A basic, aqueous solution is added to the oxidation mixture so that a separate basic water phase with a pH higher than 8.5 is formed. The alkylhydroperoxide is then decomposed in the presence of a heterogeneous catalyst which contains a metal compound immobilized on a carrier material. The metal of the catalyst is selected from the group consisting of Mn, Fe, Co, Ni, and Cu. The carrier material is stable in the presence of the separate basic water phase.
