ABSTRACT:
Benzene is converted by reductive alkylation to cyclohexylbenzene; cyclohexylbenzene by oxidation and cleavage is converted into a mixture of cyclohexylbenzene, phenol and cyclohexanone; after removal of cyclohexylbenzene from this mixture, the remaining mixture consisting essentially of phenol and cyclohexanone is effectively separated into its components by extractive distillation with a sulfolane.
