Abstract: CARBONYL-CONTAINING COMPOSITIONS, SUCH AS ALDEHYDES AND KETONES, ARE SELECTIVELY AND CONVENIENTLY PREPARED IN HIGH YIELDS AND AT HIGH EFFICIENCES BY A CATALYTIC VAPOR PHASE PROCESS WHICH COMPRISES CONTACTING UNSATURATED COMPOUNDS WITH OXYGEN IN THE PRESENCE OF A NOVEL CATALYST CONTAINING A VANADIUM OXIDE DOPED WITH AT LEAST ONE, AND PREFERENTIALLY TWO OR MORE, TRANSITION METALS OR TRANSITION METAL-CONTAINING COMPOUNDS, ONE OF WHICH IS, OR CONTAINS, PALLADIUM. THE CATALYSTS EMPLOYED ARE HIGHLY ACTIVE AND SELECTIVE AT MODERATE TEMPERATURES AND PRESSURES AND HAVE INDUSTRIALLY USEFUL LIFETIME.
