摘要：
A process for producing ethanol which comprises reacting methanol, carbon monoxide and hydrogen, characterized in that the reaction is carried out in the presence of (a) a solvent selected from the group consisting of hydrocarbons, and ethers and (b) a catalyst comprising a cobalt compound, a ruthenium compound and a tertiary phosphine in the absence of iodine, bromine, an iodine compound or a bromine compound is disclosed. According to this invention, ethanol can be produced from methanol, carbon monoxide and hydrogen in a high selectivity to neat ethanol.
