Catalytic reaction of olefins with carbon monoxide and hydrogen

Claim 1

IN A CONTINUOUS EXOTHERMIC ALDEHYDR SYNTHESIS PROCESS WHEREIN OLEFINIC COMPOUNDS CARBON MONOXIDE AND HYDROGEN ARE CONTACTED WITH A COBALT CARBONYLATION CATALYST IN AN ADIABATIC REACTION ZONE TO PRODUCE ALDEHYDES CONTAINING ONE MORE CARBON ATOM THAN SAD OLEFINS, THE IMPROVEMENT COMPRISING CONTROLLING THE TEMPERATURE LEVEL OF SAID ADIABATIC REACTION ZONE AND MAINTAINING HIGH CONCENTRATION OF COBALT CARBONYL CATALYST THROUHOUT THE CARBONYLATION REACTION ZONE, WHICH COMPRISES THE STEPS OF CONTACTING OLEFINIC COMPOUNDS, CARBON MONOXIDE AND HYDROGEN IN A REACTION ZONE UNDER CARBONYLATION CONDITIONS COMPRISING TEMPERATURES IN THE RANGE OF ABOUT 250 TO ABOUT 375* F. AND PRESSURES IN THE RANGE OF ABOUT 2500 TO ABOUT 3500 P.S.I.G. WITH A COBALT CARBONYLATION CATALYST, WITHDRAWING FROM SAID REACTION ZONE, LIQUID REACTION PRODUCTS COMPRISING ALDEHYDES AND CONTAINING DISSOLVED COBALT CARBONYL, PASSING SAID WITHDRAWN PRODUCTS THROUGH A COOLING ZONE INTO A SEPARATION ZONE, MAINTAINING SAID SEPARATION ZONE AT SUB-
