ABSTRACT:
m-Xylene is difficult to separate from p-xylene or o-xylene by conventional distillation or rectification because of the close proximity of their boiling points. m-Xylene can be readily separated from p-xylene or o-xylene by using azeotropic distillation in which the agent is an aliphatic ester. Typical examples of effective agents are: for m-xylene from p-xylene, propyl butyrate or methyl valerate; for m-xylene from o-xylene, hexyl formate or methyl valerate.
