Abstract

Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid by hydrolyzing a portion of the crude ethanol product or one or more derivative streams obtained therefrom. The one or more derivative streams comprise ethyl acetate and the hydrolyzed stream is directly or indirectly fed to the distillation zone or the hydrogenation reactor.
