Abstract

1,140,570. Catalytic hydrogenation. CHEMISCHE WERKE HULS A.G. 6 May, 1966 [8 May, 1965], No. 20032/66. Heading C2C. [Also in Division B1] Preparation of olefinically unsaturated alcohols by selective hydrogenation of the corresponding unsaturated aldehydes or ketones in the gas phase at a temperature of 150‹ to 300‹ C. wherein a catalyst is used which has a cadmium content of 30 to 70% by weight, a copper content of 15 to 70% by weight and a magnesium content of 3 to 40% by weight based on the total weight of the activating constituents reckoned as the elements and excluding any carrier present, the proportion of any carrier material present being from 0 to 90% by weight on the total catalyst including carrier material. The catalyst materials, obtained by precipitation as carbonates or hydroxides of the metals, may be used in the form of pressure mouldings or supported on specified carriers and are thermally treated prior to or simultaneously with reduction in hydrogen before use. A number of unsaturated carbocyclic and acyclic unsaturated aldehydes and ketones are specified as suitable starting materials. The vaporized ketone or aldehyde is passed over the catalyst with 1500 1.hr. of hydrogen at or above atmospheric pressure to give the desired unsaturated alcohol as well as minor amounts of the corresponding saturated alcohol and related aldehyde as by-product. Crotyl alcohol is obtained, optionally in association with butanol and/or butyraldehyde, by hydrogenation of crotonaldehyde. 2-Ethylhexenol-1 is obtained, optionally in association with 2-ethylhexanol and 2-ethylhexanal by the hydrogenation of 2-ethylhexenal-1. 2,5 - Endomethylene - 1,2,5,6 - tetrahydrobenzyl alcohol is obtained by hydrogenating 2,5- endomethylene - 1,2,5,6 - tetrahydrobenzaldehyde-1.
