Methyl ethyl ketone cannot be separated from ethanol by distillation or rectification because of the closeness of their boiling points. Methyl ethyl ketone is readily separated from ethanol by azeotropic distillation. Effective agents are amyl acetate, methyl formate, 2,2-dimethyl butane and 2,3-dimethyl butane.
