Abstract
A method is useful for the continuous production of ketones from a compound with at least one epoxide group in at least one fixed bed reactor. A catalyst composition is used with at least one noble metal and at least one metal oxide. To reduce the proportions of high-boilers which form in the reaction, an inert gas is introduced so that a carbon monoxide partial pressure of 50 mbar or less is set in the reactor.
