Abstract:
Disclosed herein are processes for alcohol production by reducing an esterification product, such as ethyl acetate. The processes comprise esterifying acetic acid and an alcohol such as ethanol to produce an esterification product. The esterification product is reduced with hydrogen in the presence of a catalyst to obtain a crude reaction mixture comprising ethyl acetate, ethanol, and at least one alcohol having at least 4 carbon atoms. The ethanol is recovered with a reduced amount of the alcohol having at least 4 carbon atoms.
