Distillation is a process used to separate components of a liquid mixture by selective boiling and condensation. The process relies on the difference in the boiling points of the constituents. When a mixture is heated, the component with the lowest boiling point will vaporize first. This vapor is then cooled and condensed back into a liquid, resulting in a separation from the original mixture. The condensed liquid, known as the distillate, will be enriched in the more volatile component.

There are several types of distillation. Simple distillation is suitable for separating liquids with significantly different boiling points or for separating a liquid from a non-volatile solute. Fractional distillation is employed when the boiling points of the components are close. This method uses a fractionating column, which provides a larger surface area for repeated vaporization and condensation cycles, leading to a more efficient separation. Steam distillation is used for temperature-sensitive compounds that might decompose at their boiling point, by introducing steam to lower the boiling temperature. Vacuum distillation is utilized for substances with very high boiling points or those that are susceptible to thermal degradation.

Distillation has widespread applications in various industries. It is crucial in the production of alcoholic beverages, refining crude oil into fuels and other products, purifying water, and in chemical synthesis and laboratory analysis. The efficiency of the separation depends on factors such as the difference in boiling points, the design of the distillation apparatus, and the operating conditions.
