Abstract
A process for preparing a ketone by conversion of a compound E which contains an epoxy group to the ketone in the presence of a mixture comprising at least one noble metal and at least one metal oxide as a catalyst system, wherein the metal oxide in the catalyst system is at least one of titanium dioxide and zirconium dioxide, and the process is conducted at 0 to 0.9 bar of hydrogen.
Claims10
A process for preparing a ketone, comprising:
- converting a compound E that comprises an epoxy group in the presence of a catalyst system to the ketone;
- wherein
- the catalyst system comprises a noble metal and a metal oxide,
- the metal oxide comprises at least one of titanium dioxide and zirconium dioxide, and
- a hydrogen pressure of the conversion is from 0 to 0.9 bar.
2 more elements
A method to convert a compound E which comprises an epoxy group to a ketone, comprising:
- conducting the conversion in the presence of a catalyst system;
- the catalyst system comprising:
- a noble metal and
- a metal oxide, wherein the catalyst system is selected from the group of systems consisting of system I, system II and system III,
- wherein
- the noble metal is at least one selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium and platinum,
- in system I the noble metal is unsupported and the metal oxide comprises at least one of titanium dioxide and zirconium dioxide;
- in system II the noble metal is supported, the noble metal support does not comprise titanium dioxide or zirconium dioxide, and the system further comprises at least one of titanium dioxide and zirconium dioxide;
- and
- in system III the noble metal is supported on zirconium dioxide as the metal oxide.
