ABSTRACT:
Phenol, cyclohexanone, and cyclohexylbenzene containing mixtures are extractively distilled to provide overhead of cyclohexylbenzene and cyclohexanone and a kettle product substantially free of cyclohexylbenzene by employing a dialkyl and/or a dicycloalkyl phthalate. Co-agents or modifiers, e.g., sulfolane, polyalkylene glycols, etc., are advantageously used in some instances.
