    摘要: PURPOSE: To prepare ethanol from methanol, CO and hydrogen, in high selectivity, by the heterogeneous reaction using cobalt, phosphate as a main catalyst, and if necessary, a platinum-group element as a cocatalyst.
    CONSTITUTION: Ethanol is prepared from methanol, CO and hydrogen, in high selectivity, by using a catalyst system comprising a main catalyst consisting of cobalt phosphate containing 0.1W500milli-atom of cobalt (as metal) per 1mol of methanol, and if necessary, a cocatalyst consisting of a platinum-group metal (pref. Ru, Rh, or Pd) containing 0.01W50milli-atom of the element (as metal) per 1mol of methanol, in a heterogeneous reaction system, and reacting under a pressure of 150W 450kg/cm
    2 at 180W280°C. The combined use of the cocatalyst suppresses the by- production of oxygen-containing compounds other than ethanol. The catalyst can be separated by simple filtration, and recovered and reused with little recovery loss.
