(11) A B S T R A C T The invention relates to a process for preparing cyclohexanol and/or cyclohexanone, in which cyclohexene in a feed stream containing cyclohexene, cyclohexane and benzene is hydrated into cyclohexanol and/or oxidized into cyclohexanone, the cyclohexanol and/or cyclohexa- none formed is separated from the reaction mixture thus obtained and the remaining cyclohexane and benzene are recycled to a preconnected cyclohexene preparation section, part of the stream that is recycled to the cyclohexene preparation section being subjected to a dehydroge- nation reaction and the remaining part to a hydrogenation reaction, and the reaction streams thus obtained being combined to form the feed stream to the hydration and/or oxidation step.
