Abstract
Provided is an industrially superior method for producing cyclohexyl alkyl ketones, which solves the problems in process reduction and in disposal of wastes such as metals. An aromatic ketone represented by a formula (1) is nuclear-hydrogenated with pressurized hydrogen and in the presence of a solvent at a temperature of from 20 to 120° C., in the presence of a catalyst that carries from 0.1 to 20% by weight of a ruthenium atom on the carrier, thereby producing a cyclohexyl alkyl ketone represented by a formula (2): provided that, in the formula (2), n indicates an integer of from 1 to 3; R represents a hydroxyl group, a cyclohexyl group, an alkyl group having from 1 to 4 carbon atoms, or an acyl group having from 1 to 4 carbon atoms
