ABSTRACT:
Ethyl benzene is difficult to separate from p-xylene by conventional distillation or rectification because of the closeness of their boiling points. Ethyl benzene can be readily separated from p-xylene by extractive distillation. An effective agent is 5-methyl-2-hexanone, also called methyl isoamyl ketone.
