Abstract: The present invention provides a solid catalyst with which to synthesize liquid-phase methanol from carbon monoxide and hydrogen which are under pressure, in a solution such as methanol, without executing separation or recirculation. A solid catalyst, in which an ion-exchange resin anion-exchanged to be an alcoxide type is combined with a transition metal such as a Raney type, powder type or supported type, is used for synthesizing methanol from carbon monoxide and hydrogen in a solution such as methanol.
