what is fractional distillation

Fractional distillation is a technique for the separation of miscible liquids. It is a distillation technique used for the separation of liquids which dissolve in each other. Fractional distillation is a process of separating the components of a mixture by repeated distillations and condensations.
The principle of fractional distillation is that different liquids boil at different temperature. The miscible liquids boil at different temperature and evaporate at different temperature.
When the mixture is heated, the liquid with lower boiling point boils and turns into vapours. So the mixture is heated to a temperature at which one or two components of the mixture will vaporise. Fractional distillation involves repeated distillations and condensations.
