Abstract
A supported gold catalyst is used for selective oxidation. In particular, an alcohol or ketone is oxidized to produce the corresponding carboxylic acid, an alcohol is oxidized to produce the corresponding ketone, and xylene is oxidized to produce the corresponding mono-alcohol or di-alcohol.
Claims36
A process for the oxidation of a primary alcohol to produce the corresponding carboxylic acid comprising contacting the alcohol with a catalytic amount of a supported heterogeneous catalyst consisting essentially of gold, wherein the catalyst is supported on a support material selected from SiO2, Al2O3, carbon, TiO2, MgO, and zirconia and wherein the reaction is performed in the liquid phase.
A process for the oxidation of a ketone to produce the corresponding carboxylic acid comprising contacting the ketone with a catalytic amount of a supported heterogeneous catalyst consisting essentially of gold, wherein the cataylst is supported on a support material selected from SiO2, Al2O3, carbon, TiO2, MgO, and zirconia and wherein the reaction is performed in the liquid phase.
A process for the oxidation of a secondary alcohol to produce the corresponding ketone comprising contacting the secondary alcohol with a catalytic amount of a supported heterogeneous catalyst consisting essentially of gold, wherein the catalyst is supported on a support material selected from SiO2, Al2O3, carbon, TiO2, MgO, and zirconia and wherein the reaction is performed in the liquid phase.
A process for the selective oxidation of xylene to the corresponding mono-alcohol or di-alcohol comprising contacting the xylene with an catalytic amount of a supported heterogeneous catalyst consisting essentially of gold, wherein the catalyst is supported on a support material selected from SiO2, Al2O3, carbon, TiO2, MgO, and zirconia and wherein the reaction is performed in the liquid phase.
