THE PROCESS FOR THE PRODUCTION OF UNSATURATED CARBONYLIC REACTION PRODUCTS COMPRISING LOWER ALPHA, BETA-UNSATURATED ALIPHATIC ALDEHYDES, WHICH COMPRISES CONTACTING AN OLEFIN HAVING FROM THREE TO TEN CARBON ATOMS TO THE MOLECULE AND AN OXYGEN-CONTAINING GAS, IN A MOL RATIO OF OXYGEN TO SAID OLEFIN BELOW ABOUT 1, WITH A COPPER-CONTAINING CATALYST, AT A TEMPERATURE OF FROM ABOUT 275 TO ABOUT 400*C., IN A FIRST REACTION ZONE, ADDING OXYGEN-CONTAINING GAS TO UNCONVERTED OLEFIN-CONTAINING EFFLUENCE FROM SAID FIRST REACTION ZONE IN THE CONTROLLED AMOUNT RESULTING IN THE FORMATION OF AN ADMIXTURE CONTAINING A MOL RATIO OF OXYGEN TO OLEFINIC HYDROCARBONS ABOVE ABOUT 1, AND CONTACTING THE RESULTING ADMIXTURE WITH A COMBINATION CATALYST CONSISTING ESSENTIALLY OF THE COMBINATION OF (A) A METAL SELECTED FROM THE GROUP CONSISTING OF BISMUTH, COBALT AND NICKEL WITH (B) A METAL FROM THE LEFT HAND COLUMN OF GROUP VI OF THE PERIODIC TABLE OF THE ELEMENTS AND WITH (C) OXYGEN IN A SECOND REACTION ZONE, AT A TEMPERATURE WHICH IS ABOVE THAT MAINTAINED IN SAID FIRST REACTION ZONE AND WHICH IS IN THE RANGE OF FROM ABOUT 375 TO ABOUT 500*C., THEREBY REACTING OLEFINS WITH OXYGEN WITH THE FORMATION OF CARBONYLIC REACTION PRODUCTS COMPRISING LOWER ALPHA, BETA-UNSATURATED ALIPHATIC ALDEHYDES IN SAID REACTION ZONES.
