57 A process for producing a mixed alcohol by contacting a synthesis gas with a catalyst, wherein the catalyst is a solid substance prepared by:
calcining a mixture of (A) a copper or zinc compound, (B) a compound of at least one metal selected from iron, cobalt, and nickel, and (C) a compound of at least one metal selected from the metals belonging to Groups II-VII of the Periodic Table; impregnating the above-calcined product with (D) an alkali metal compound and/or an alkaline earth metal compound; calcining the resulting mixture; and reducing the thus-calcined product. The selectivity of the mixed alcohol is high in the process of the present invention. This is one of the advantages of the present invention. Furthermore the proportion of alcohols other than methanol in the mixed alcohol is relatively high, and thus the mixed alcohol is suitable for use as an alcohol component to be compounded to gasoline.
