Phenol production methods

WebMost of the phenol used today is produced from benzene, through either hydrolysis of chlorobenzene or oxidation of isopropylbenzene (cumene). Hydrolysis of chlorobenzene … Cyclohexylbenzene can replace isopropylbenzene. Via the Hock rearrangement, cyclohexylbenzene hydroperoxide cleaves to give phenol and cyclohexanone. Cyclohexanone is an important precursor to some nylons. Starting with the alkylation of benzene with mixture of 1 and 2-butenes, the cumene process produces phenol and butanones.
