A process for converting methanol to ethanol which comprises reacting methan ol and carbon monoxide in the presence of a catalyst to produce a product comprising at least 25 mole% methyl acetate and, in some instances, acetic acid. The aceti c acid then is reacted with at least one alcohol to produce at least one acetate selected from methyl acetate, ethyl acetate, and butyl acetate. The at least one acetate ( if produced) and the methyl acetate produced as a result of reacting methanol and carbon monoxide then are hydrogenated to produce ethanol. Syngas may be produced from biomas s to produce all or a portion of the methanol, hydrogen, and carbon monoxide requirements for the process. |
