IN THE PROCESS OF MAKING C5 ALOHOLS FROM C4 OLEFINS BY THE OXO PROCESS, THE IMPROVED METHOD OF OPERATION WHICH COMPRISES INTRODUCING A C4 OLEFIN CHARGE INTO AN OXOLATION ZONE MAINTAINED UNDER CARBONYLATION CONDITIONS AND ALSO INTRODUCING THERETO COBALT CATALYST AND BOTH FRESH AND RECYCLED H2 PLUS CO SYNTHESIS GAS, MAINTAINING A LIQUID PHASE OF CONTROLLED TEMPERATURE IN THE OXOLATION ZONE BY INTRODUCING C4 HYDROCARBONS THERTO AT SPACED LEVELS AS A COOLANT LIQUID WHICH IS SUBSTANTIALLY FREE FROM DISSOLVED SYTHESIS GAS, COOLING THE EFFLUENT STREAM FROM THE OXOLATION ZONE TO A TEMPEATURE OF ABOUT 100*F. AND DEPRESSURING SAID STREAM TO A PRESSURE IN THE RANGE OF ABOUT 700 TO 1500 P. S. I., COMPRESSING AND RECYCLING GAS SEPARATED FROM THE STREAM AT THE PRESSURE IN SAID RANGE, REMOVING SUBSTANTIALLY ALL REMAINING SYNTHESIS GAS FROM SAID STREAM AT LOWER PRESSURE, THEN FRAC-
