Cyclohexylbenzene is the organic compound with the formula C₆H₅-C₆H₁₁. It is a derivative of benzene with a cyclohexyl substituent (C₆H₁₁). A colorless liquid, it is produced by the alkylation of benzene with cyclohexene.[1] It is generated by the hydrodesulfurization of dibenzothiophene.[2]

A route to phenol analogous to the cumene process begins with cyclohexylbenzene, which is oxidized to a hydroperoxide, akin to the production of cumene hydroperoxide. Via the Hock rearrangement, cyclohexylbenzene hydroperoxide cleaves to give phenol and cyclohexanone. Cyclohexanone is an important precursor to some nylons.[3]
