摘要：
Disclosed herein are processes for alcohol production by reducing an esterification product, such as ethyl acetate. The processes comprise esterifying an excess molar ratio of acetic acid with an alcohol, such as ethanol, to produce the esterification product. The esterification product is reduced with hydrogen in the presence of a catalyst to obtain a crude reaction mixture comprising the alcohol, in particular ethanol, which may be separated from the crude reaction mixture.
