PURPOSE:To obtain the titled substance from carbon monoxide and hydrogen in high yield at a low cost, by using a catalyst supporting rhodium, scandium, etc., on a carrier and a catalyst supporting rhodium, iridium and/or iron, etc., on a carrier in combination. CONSTITUTION:Carbon monoxide is reacted with hydrogen in the presence of (A) a catalyst supporting rhodium, scandium, iridium and/or lithium on a carrier and (B) a catalyst supporting rhodium, and (i) iridium and/or (ii) iron or molybdenum on a carrier in combination to give the titled substance. The catalyst is prepared by dissolving a metal compound in a solvent, e.g. water methanol, adding a carrier to the resultant solution, impregnating the carrier with the solution, distilling away the solvent, drying the impregnated carrier, and if necessary heating the resultant carrier to support the metal compound on the carrier. The carrier has 10-1,000m<2>/g specific surface area and >=10Angstrom pore diameter, and particularly silica based carrier is preferred. |
