Fractional Distillation

Fractional distillation is used for the separation of a mixture of two or more miscible liquids for which the difference in boiling points is less than 25 K. The apparatus for fractional distillation is similar to that of simple distillation, except that a fractionating column is fitted in between the distillation flask and the condenser.


This video explains how to separate a mixture of ethanol and water by fractional distillation.
