Abstract:
The present invention relates to a process for producing ethanol by methyl acetate hydrogenolysis. The process comprises the step of reacting carbon monoxide and methanol in a reaction medium to form a reaction solution that comprises acetic acid and from 0.5 to 25 wt. % methyl acetate. The process further comprises the step of esterifying the acetic acid and feeding the methyl acetate to a distillation column to remove alkyl halides. The process further comprises the steps of reacting the methyl acetate stream that does not contain alkyl halides and hydrogen in the presence of a second catalyst to form an alcohol product that comprises ethanol and/or methanol.
