Process for preparing ketones from epoxides

摘要

Preparing ketone from a compound comprising at least one epoxide group, using a mixture comprising at least one noble metal and at least one metal oxide, preferably titanium dioxide and/or zirconium dioxide as a catalyst system, and at a pressure of 0-0.9 bar hydrogen, is claimed. An independent claim is also included for the catalyst system comprising noble metal and metal oxide, where when the noble metal is unsupported, then the metal oxide of the catalyst system comprises titanium dioxide or zirconium dioxide, when the noble metal is supported, then the carrier does not comprise titanium dioxide and/or zirconium dioxide, and the system additionally comprises at least one metal oxide comprising titanium dioxide or zirconium dioxide, or the noble metal is supported on zirconium dioxide as a metal oxide.
