Fractional distillation is a type of distillation which involves the separation of miscible liquids. The process involves repeated distillations and condensations and the mixture is usually separated into component parts. The separation happens when the mixture is heated at a certain temperature where fractions of the mixture start to vaporize.

The basic principle of this type of distillation is that different liquids boil and evaporate at different temperatures. So when the mixture is heated, the substance with lower boiling point starts to boil first and convert into vapours.

$\purple{Applications \: of \: Fractional \: Distillation}$

• Fractional distillation is used for the purification of water as well as separating acetone and water.

• Fractional distillation is used in several industries like oil refineries and chemical plants mainly for purification and separation of many organic compounds.

• Fractional distillation is also used for the separation of (liquefied) air. Components like liquid nitrogen and oxygen as well as concentrated argon are obtained.

• Distillation is used in the production of high-purity silicon from chlorosilanes. The silicon is widely used in

semiconductors.
