Abstract: An improved process for the preparation of cyclohexanone from benzene. Benzene is hydrogenated in a gaseous phase in a hydrogenation zone to form cyclohexane; cyclohexane is oxidized in a liquid phase to form a mixture containing cyclohexanol and cyclohexanone; and cyclohexanone is separated from this mixture and is catalytically dehydrogenated to form cyclohexanone and a hydrogen containing gas. The resulting hydrogen containing gas is introduced into a washing zone wherein it is washed with cyclohexane or benzene and the hydrogen gas thus purified is fed into the hydrogenation zone.
