Abstract
PURPOSE: To prepare ethanol in high converion and selectivity, without purification, by hydrogenating acetaldehyde in the presence of a proper amount of methanol or methanol and water, using a ruthenium (compound) catalyst.
CONSTITUTION: The preparation of ethanol by the hydrogenation of acetaldehyde is carried out in the presence of methanol or methanol and water, using ruthenium or a ruthenium compound (e.g. ruthenium dioxide, ruthenium chloride, etc.) as a catalyst. The amount of methanol is 0.1W10mol, pref. 0.5W5mol/1mol of acetaldehyde, and in the case of using water together with methanol, the amount of water is 0.1W10mol, pref. 0.5W5mol/1mol of acetaldehyde.
