Tislausprosessi, or distillation, is a fundamental separation technique used to purify liquids by selectively boiling and condensing components. It relies on the principle that different substances have different boiling points. The process begins by heating a mixture in a vessel, typically a distillation flask. As the temperature rises, the component with the lowest boiling point will vaporize first. This vapor then travels up into a condenser, which is cooled, usually by circulating water. The cooling causes the vapor to condense back into a liquid, which is then collected in a separate receiving vessel. This collected liquid is enriched in the more volatile component. The remaining liquid in the distillation flask will be enriched in the less volatile component.

There are various types of distillation, each suited for different applications. Simple distillation is effective for separating liquids with significantly different boiling points or for separating a liquid from a non-volatile solute. Fractional distillation, employing a fractionating column, is used when the boiling points of the components are close. The column provides a larger surface area for repeated vaporization and condensation cycles, leading to a more efficient separation. Other methods include steam distillation, often used for temperature-sensitive compounds, and vacuum distillation, which lowers the boiling points of substances by reducing the pressure, making it suitable for high-boiling or thermally unstable materials. Distillation is widely employed in industries such as petroleum refining, alcohol production, and chemical manufacturing.
