Abstract
The hydrogenation of a - ethyl - b - propylacrolein to produce a -ethyl hexaldehyde, 2-ethyl-1-hexanol, and normal heptane is effected by hydrogen, in the liquid or vapour phase, in presence of a hydrogenation catalyst such as nickel. The catalyst may be made by impregnating filter-stone with a nickel salt and reducing with hydrogen or by heating a nickel-silicon alloy with a solution of caustic soda. Preferably a small proportion of chromium is present in the catalyst. In examples, the hydrogenation is effected (1) in a steel bomb at 100 DEG C. and 900 lb. pressure with a catalyst prepared from a nickel-silicon alloy; (2) with nickel at 150 DEG C. and 500--800 lb. pressure; (3) in the vapour phase with a nickel catalyst containing chromium at atmospheric pressure at 158 DEG C.; (4) in the vapour-phase using 100 mols. of hydrogen to one of the aldehyde with a nickel-chromium catalyst on a carrier at 194 DEG C. and 20 lb. pressure. If a deficiency of hydrogen is employed the products will contain heptylene which may be converted to heptane by further treatment.ALSO:The hydrogenation of a -ethyl b -propyl acrolein to produce a -ethyl hexaldehyde, 2-ethyl-1-hexanol and normal heptane is effected by hydrogen in the liquid or vapour phase, in presence of a hydrogenation catalyst such as nickel.
