Date Sep. 19, 1991.The present invention provides aqueous catalyst solutions useful for oxidation of olefins to carbonyl products, comprising a palladium catalyst, a polyoxoacid or polyoxoanion oxidant comprising vanadium, and chloride ions. It also provides processes for oxidation of olefins to carbonyl products, comprising contacting olefin with the aqueous catalyst solutions of the present invention. It also provides processes for oxidation of olefins to carbonyl products by dioxygen, comprising contacting olefin with the aqueous catalyst solutions of the present invention, and further comprising contacting dioxygen with the aqueous catalyst solutions. The present invention also provides a process for the oxidation of palladium(0) to palladium(II) comprising contacting the palladium(0) with an aqueous solution comprising chloride ions and a polyoxoacid or polyoxoanion oxidant comprising vanadium.

Abstract: 2077549 9113852 PCTABS00007 This invention is to the production of methyl ethyl ketone (MEK) from mixed normal butenes using polyoxoanion oxidants in an aqueous solution, catalyzed by palladium and preferably containing minor amounts of dissolved chloride ion. An intermediate MEK stream is hydrogenated to remove trace amounts of butyraldehyde from the product MEK stream.
