Abstract (en)

[origin: WO2006046852A1] The invention relates to a process for the preparation of cyclohexanol and cyclohexanone from benzene whereby the process comprises the following steps: a. a partial hydrogenation step wherein benzene in the presence of a metal catalyst is partially hydrogenated producing a mixture comprising cyclohexene and unconverted benzene, b. a step wherein a mixture as produced in step a is hydrated producing a mixture comprising cyclohexanol and/or oxidized in the presence of a metal catalyst producing a mixture comprising cyclohexanone or a mixture comprising cyclohexanol and cyclohexanone, c. a step wherein cyclohexanol and/or cyclohexanone is separated from the mixture obtained in step b comprising unconverted benzene, cyclohexanol and/or cyclohexanone, d. a hydrogenation step wherein a mixture comprising unconverted benzene as obtained in step c is hydrogenated in the presence of a metal catalyst into cyclohexane and e. an oxidation step wherein a mixture as produced in step d comprising cyclohexane is oxidized producing a mixture comprising cyclohexanol and cyclohexanone.
