Catalyst and process for the catalytic heterogeneous gasphase oxidation of alkenes and cycloalkenes by the Wacker route

摘要

The invention relates to a catalyst as well as a process for the catalytic heterogeneous gas-phase, oxidation of an alkene or cycloalkene to the corresponding ketone or aldehyde in the presence of H₂O and O₂, the catalyst containing a vanadium and a palladium component mounted on a carrier, the improvement being that the surface of the carrier is covered with hydroxyl groups and the vanadium is present in the form of a surface vanadate.
