Unsaturated carboxylic acids may be subjected to a reduction process in which the resulting product retains the unsaturation of the starting acids by effecting the reaction in the presence of a catalyst comprising cadmium and rhenium composited on a solid support such as alumina. If so desired, the catalyst composite may also contain a noble metal of Group VIII of the Periodic Table.
