2. Azeotrope distillation using benzene:The second method uses a third component like benzene, toluene, carbon tetrachloride and diethyl ether in azeotropic distillation operation. These dehydrating agents alter the boiling point and partial pressure of ethanol and water so that when heat supplied to the solution, one of the components boiling point range is changed and so we can separate them using distillation method.
