Fractional distillation is the separation of a mixture into its component parts, or fractions, separating chemical compounds by their boiling point by heating them to a temperature at which one or more fractions of the compound will vaporize.

Fractional Distillation is a separation technique that is used for liquids that dissolve in each other.
Liquids that dissolve in each other are called miscible.
A liquid can be separated from a mixture
of liquids in a solution by this process.

fractional distillation
A process by which a chemical compound is separated into components by distillation. In fractional distillation the compound is heated and, as each of its constituent components comes to a boil, its vapors are separated and cooled, so it can be removed in its pure form. Fractional distillation is used to refine petroleum. See also distillation .
Uses of Distillation
Distillation is used for many commercial processes, such as the production of gasoline, distilled water, xylene, alcohol, paraffin, kerosene, and many other liquids. Gas may be liquefied and separate. For example: nitrogen, oxygen, and argon are distilled from air.
Types of Distillation
Types of distillation include simple distillation, fractional distillation(different volatile 'fractions' are collected as they are produced), and destructive distillation (usually, a material is heated so that it decomposes into compounds for collection).
Simple Distillation
Simple distillation may be used when the boiling points of two liquids are significantly different from each other or to separate liquids from solids or nonvolatile components. In simple distillation, a mixture is heated to change the most volatile component from a liquid into vapor. The vapor rises and passes into a condenser. Usually, the condenser is cooled (e.g., by running cold water around it) to promote condensation of the vapor, which is collected.
