Separation of cyclohexylbenzene from a cyclohexylbenzene- cyclohexanone- phenol admixture

摘要

Cyclohexylbenzene is separated from a cyclohexylbenzene- cyclohexanone- phenol admixture by liquid-liquid extraction with a non- polar solvent such as hexadecane and a polar solvent, such as sulfolane, diethylene glycol, or mixtures with water. Cyclohexylbenzene is separated from the non-polar phase by fractional distillation. Phenol and cyclohexanone are separated from the polar solvent by fractional distillation.
