Process for producing phenols.

摘要

A process for producing a phenol from the steps of: (a) partially hydrogenating a benzene, followed by separating the reaction mixture into respective components of a cyclohexene, a cyclohexane and a benzene; (b) oxidizing or hydrating the separated a cyclohexene into oxygen-containing compounds of a cyclohexane; (c) dehydrogenating the oxygen-containing compounds of a cyclohexane into a phenol; (d) dehydrogenating the cyclohexane separated in step (a) to convert the cyclohexane into a benzene; and (e) returning a part or all of hydrogen formed in steps (c) and (d) back to step (a). o
