Disclosed is a process for the preparation of cyclohexyl cyclohexanone (CHA). Cyclohexanone is self-condensed to yield a mixture of cyclohexylidene cyclohexanone (CHDA), water, and unconverted cyclohexanone. The CHDA in the mixture is directly hydrogenated to CHA under an atmosphere of hydrogen and in the presence of a suitable catalyst, the presence of water and cyclohexanone not affecting the reaction.
