ABSTRACT:
A cyclic ketone/alcohol mixture is prepared by catalytic oxidation of the corresponding cycloalkane or catalytic decomposition of the corresponding cycloalkyl hydroperoxide. Gold supported on a porous crystalline silicate containing less than about 2 wt. % aluminum or a crystalline phosphate is used as a catalyst. The support material optionally contains one or more heteroatoms.
