摘要：
In a hydrogenation processes, a second lower temperature hydrogenation reactor is used to control the concentration of impurities, namely ethyl acetate, acetaldehyde, and acetal, prior to separating the reaction mixtures. Controlling impurities reduces the need for separation capital and improves overall efficiencies for recovering alcohols.
