Abstract
A catalyst composition is useful for producing a ketone from a compound containing at least one epoxide group, and the catalyst composition contains at least one precious metal; and at least one mixed oxide; wherein the mixed oxide contains zirconium dioxide and silicon dioxide; wherein the precious metal is supported and the support is not entirely made of the mixed oxide; and wherein a mass ratio of zirconium dioxide to silicon dioxide in the mixed oxide is 86:14 to 99.9:0.1.
Claims17
A catalyst composition, comprising:
- at least one precious metal;
- and
- at least one mixed oxide;
- wherein the mixed oxide comprises zirconium dioxide and silicon dioxide;

4 more elements
A process for producing a ketone, comprising:
- reacting a compound containing at least one epoxide group in the presence of a catalyst composition;
- wherein the catalyst composition comprises at least one precious metal and at least one mixed oxide, wherein the mixed oxide comprises zirconium dioxide and silicon dioxide, wherein the precious metal is supported on a support and wherein a mass ratio of zirconium dioxide to silicon dioxide in the mixed oxide is 86:14 to 99.9:0.1, and wherein the support is the mixed oxide or the support does not consist of the mixed oxide.
