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.
Claims27
A method of oxidizing a cycloalkane in a reaction mixture to form a product mixture containing a corresponding alcohol and ketone, the method comprising contacting the reaction mixture with a source of oxygen in the presence of a catalytic effective amount of gold supported on a porous crystalline silicate containing less than about 2 wt. % aluminum or a crystalline phosphate wherein the support comprises a three-dimensional framework with cavities and channels.
A method for decomposing a cycloalkyl hydroperoxide in a reaction mixture to form a product mixture containing a corresponding alcohol and ketone, the method comprising contacting the reaction mixture with a catalytic effective amount of gold supported on a porous crystalline silicate or phosphate wherein the support comprises a three-dimensional framework with cavities and channels.
The method of claim 8 wherein the porous crystalline silicate support has a structure selected from the group consisting of BEA, FAU, MFI, MEL, MOR, MTW, MTT, MCM-22, MCM-41, MCM-48, NU-1.
