Abstract

A process for the manufacture of higher ketones by reacting an aldehyde with a ketone in the presence of hydrogen over a catalyst system which contains, firstly, oxides or salts of the rare earth metals and, secondly, metals of group VIII of the periodic table of the elements. The process gives numerous higher ketones, required, for example, as solvents for surface coatings, or as scents, with high conversions and good selectivities, and therefore more simply and more economically than conventional methods.
