摘要：
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 may be recovered using an extractive separation. 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.
