Abstract
A process for making a hydrocarbyl vinyl ketone is disclosed. In this process a ketone having the structural formula CH.sub.3 COR, where R is lower alkyl, phenyl or C.sub.7 -C.sub.8 aralkyl, is reacted with methanol in an oxygen-containing atmosphere in the presence of a catalyst system comprising a catalytically effective amount of iron on an inert support. In another preferred embodiment, the catalyst system comprises a catalytically effective amount of a precious metal selected from the group consisting of silver and gold, in addition to iron, supported on an inert material.
