摘要: A process for recovering ethanol obtained from the hydrogenation of acetic acid. The crude ethanol product is separated in a column to produce a distillate stream comprising acetaldehyde and ethyl acetate and a residue stream comprising ethanol, acetic acid, ethyl acetate and water. The ethanol product is recovered from the residue stream.

摘要: In one embodiment, the invention is to a process for producing multi-carbon alcohols, including butanol and/or hexanol. The process comprises the step of reacting ethanol in a reactor to form a crude product comprising butanol, ethanol, and water. The process further comprises the step of separating at least a portion of the crude product in a first distillation zone to form a first distillate comprising ethanol and a first residue comprising butanol, and water. The process further comprises the step of separating at least a portion of the first residue in a second distillation zone to form a second distillate and a second residue comprising butanol.
