ABSTRACT:
Aliphatic alcohols are produced by an improved hydrogenation of the corresponding saturated aliphatic aldehydes in the presence of organo-sulfur impurities by partially hydrogenating the aldehydes in a first hydrogenation zone in the presence of a sulfided hydrogenation catalyst at a temperature within the range of from about 180.degree. to 260.degree. C., followed by completion of the hydrogenation in the second hydrogenation zone in the presence of a metallic nickelcontaining hydrogenation catalyst. The second hydrogenation zone employs a lower temperature than is used in the first and is selected within the range of from about 175.degree. to 250.degree. C.
