Abstract

Aldehydes are preferentially hydrogenated in a mixture of aldehydes and olefines by hydrogenating the mixture at a temperature below 260 DEG C. and at a pressure of 7 to 70 kg. sq. cm. in the presence of added water using a hydrogenation catalyst, which is effective at temperatures below 260 DEG C., whereby the aldehydes are converted to the corresponding alcohols and hydrogenation of the olefines is appreciably inhibited. Suitable catalysts are, for example, nickel, cobalt, nickel tungsten sulfide, cobalt molybdate and copper chromite and they can be used in pelleted or granulated form as such or deposited on a carrier such as diatomaceous earth or kieselguhr. The water may be introduced in liquid or vapour phase to the mixture of aldehydes and olefines before or after the mixture is introduced to the hydrogenation stage. The mixture of aldehydes and olefines used as starting material is usually obtained by removing carbon monoxide, hydrogen and catalytic metals from the product obtained in the hydroformylation stage of the oxo process. It is preferred to use liquid volume ratios of water to hydroformylation products of from 0.15:1 to 2:1. In the examples, the product obtained by the hydroformylation of heptanes, consisting mainly of aldehydes and olefines, is hydrogenated in the presence of added water at a temperature below 260 DEG C. and a pressure of 35 kg./sq. cm., using a nickel or kieselguhr catalyst, to give the corresponding alcohols, the olefins present in the starting material being largely unaffected by the hydrogenation.
