PURPOSE:In preparing acetic acid, aldehyde, and/or ethanol by reacting carbon monoxide with hydrogen in the presence of a catalyst, to obtain the desired compound selectively by using ruthenium and a specific metal such as lithium, sodium, etc. CONSTITUTION:Carbon monoxide is reacted with hydrogen in a gaseous phase by using a catalyst obtained by combining (a) ruthenium with (b) at least one metal selected from lithium, sodium, vanadium, and zirconium, to obtain acetic acid, acetaldehyde, and/or ethanol in high selectivity without using an expensive and scarce rhodium catalyst. The catalyst component is usually supported on a carrier, preferably having 1-1,000m<2>/g surface area, especially a silica carrier, reduced at 250-550 deg.C so that ruthenium is substantially activated in a metal state, and used for the reaction. |
