IN A PROCESS FOR CONVERSION OF AN OLEFINIC HYDROCARBON TO A CARBONYL COMPOUND SELECTED FROM THE GROUP CONSISTING OF ALDEHYDES AND KETONES BY OXIDIZING AN OLEFINIC CARBON ATOM OF SAID OLEFINIC HYDROCARBON TO A CARBONYL GROUP BY CONTACTING SAID OLEFINIC HYDROCARBON AND OXYGEN AT A TEMPERATURE BETWEEN 50*C. AND 160C. AND AT A PH BETWEEN 0.5 AND 6 WITH WATER AND A CATALYST OF (A) A SALT OF A NOBLE METAL SELECTED FROM THE GROUP CONSISTING OF PALLADIUM, IRIDIUM, RUTHENIUM, RHODIUM AND PLATINUM (B), AS A REDOX SYSTEM, AN INORGANIC SALT OF A MEAL SHOWING SEVERAL VALENCE STATES UNDER THE REACTION CONDITIONS APPLIED, THE IMPROVEMENT OF CONTACT ING SAID OLEFINIC HYDROCARBON, OXYGEN, AND SAID CATALYST IN THE PRESENCE OF A DILUENT GAS SELECTED FROM THE GROUP CONSISTING OF CARBON MONOXIDE AND HYDROGEN.
