PROCESS FOR THE CATALYTIC ADDITION OF CARBON MONOXIDE AND AN OLEFINIC HYDROCARBON FOR THE PRODUCTION OF ORGANIC OXYGENATED COMPOUNDS WHICH COMPRISES CONTACTING A HYDROCARBON SELECTED FROM THE GROUP CONSISTING OF ETHYLENE, PROPYLENE AND BUTYLENE WITH CARBON MONOXIDE IN THE PRESENCE OF A DILUENT SELECTED FROM THE GROUP CONSISTING OF BENZENE AND TOLUENE AND AN AQUEOUS CATALYST SOLUTION OF COBALT SULFATE, FREE OF METALLIC HALOGEN COMPOUNDS AND CONTAINING AN ADDITIONAL SULFATE SELECTED FROM THE GROUP CONSISTING OF IRON SULFATE, MAGNESIUM SULFATE AND ZINC SULFATE, AT A TEMPERATURE BETWEEN 190* AND 200*C. AND AT A PRESSURE BETWEEN 200 AND 250 KILOGRAMS PER SQUARE CENTIMETER AND RECOVERING THE OXYGENATED COMPOUNDS FORMED.
