PURPOSE: To prolong the catalytic life and improve the selectivity in the production of the title compound useful in industrial field as an industrial chemical or solvent from a synthetic gas containing carbon monoxide and hydrogen, by using a specific inexpensive cobalt catalyst. n CONSTITUTION: The objective compound is produced by reacting a synthetic gas containing carbon monoxide and hydrogen, preferably a gas containing CO and H 2 at a molar ratio (CO/H 2 ) of 1/20W20/1, preferably 1/10W10/1 at e.g., 150W450°C at a space velocity of 1,000W10000/h under a reaction pressure of 5W150kg/cm 2 in the presence of a cobalt catalyst produced by supporting a cobalt carbonyl compound on an oxide carrier. The above reaction is preferably carried out in the presence of an alkaline-earth metal element as a cocatalyst. The cobalt carbonyl compound is e.g., dicobalt octacarbonyl [CO 2 (CO) 8 ], etc., and the oxide used as a catalyst carrier is silica gel. n COPYRIGHT: (C)1989,JPO&Japio |
