Fractional distillation is advanced type of distillation in which the component of the liquid mixture can be separated more accurately. The difference between simple distillation and fractional distillation is that simple distillation is used for the liquid mixture where the boiling points of the components are differ by greater than 25 degree Celsius where as fractional distillation is used if the difference in the boiling points of components of liquid mixture is less than 25 degree Celsius. Fractional distillation also follows the same techniques of boiling and condensation but in more accurate way due to a special apparatus called fractionating column Fractionating column is along tube which contain partitions so that it allows the liquids of near boiling points also to seperate The apparatus of fractional distillation is similar to that of simple distillation but it includes fractionating column connected to round bottomed flask and connected to condenser. This helps to separate the components of mixture with near boiling points to separate.
