Abstract

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.

CONSTITUTION: The objective compound is produced by reacting a synthetic gas containing carbon monoxide and hydrogen, preferably a gas containing CO and H₂ at a molar ratio (CO/H₂) of 1/20-20/1, preferably 1/10-10/1 at e.g., 150-450^oC at a space velocity of 1,000-10000/hr under a reaction pressure of 5-150 kg/cm² 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 [CO₂(CO)₈], etc., and the oxide used as a catalyst carrier is silica gel.
