PURPOSE:To obtain the titled compound economically in high selectivity and conversion, by reacting carbon monoxide with hydrogen using a catalyst system consisting of a rhodium-based catalyst and an iridium catalyst containing iron or iron and rhodium. CONSTITUTION:The objective compound can be produced by reacting carbon monoxide with hydrogen preferably under 0-250kg/cm<2>G pressure at 180-350 deg.C using a catalyst system consisting of (A) a catalyst selected from A1 a catalyst obtained by supporting rhodium on a carrier, A2 a catalyst obtained by supporting rhodium, lithium or manganese on a carrier, and A3 a catalyst obtained by supporting rhodium, mangenese, iridium and/or lithium on a carrier and (B) a catalyst selected from B1 a catalyst obtained by supporting iridium and iron on a carrier and B2 a catalyst obtained by supporting iridium, iron and rhodium on a carrier. The catalyst A and B are used in the form of a mixture, or by setting the catalyst A at the upper layer and the catalyst B at the lower layer. |
