Abstract

Aldehydes, free from olefinic unsaturation, are reduced to the corresponding alcohols by treatment with hydrogen in the presence of a Ru, Rh, Ru-Pd or Ru-Rh catalyst at 90-135 DEG C. under a pressure of 350-3500 p.s.i.g. It is preferred to use as starting materials, saturated aldehydes produced by reduction of mono-olefinically unsaturated aldehydes with hydrogen in the presence of a Pd catalyst at 20-80 DEG C. Preferred conditions for the reduction of the aldehyde to alcohol are temperatures of 100-125 DEG C. and pressures of 500-1500 p.s.i.g. The preferred catalysts are Ru and Ru-Pd supported on a solid carrier. Examples relate to the preparation of butyraldehyde, from crotonaldehyde, and its subsequent reduction to n-butyl alcohol. The process is illustrated by schematic drawings (not shown).
