Tislauslämpötila

Tislauslämpötila, or distillation temperature, refers to the specific temperature at which a substance boils and turns into vapor during the process of distillation. This temperature is a characteristic property of a pure substance at a given pressure. For mixtures, the boiling point is not a single fixed temperature but rather a range. As a mixture is heated, the component with the lowest boiling point will vaporize first. This vapor, enriched in the more volatile component, is then condensed and collected, separating it from the less volatile components.

The precise distillation temperature is influenced by atmospheric pressure. At lower pressures, substances boil at lower temperatures, and at higher pressures, they boil at higher temperatures. This principle is utilized in vacuum distillation, where reduced pressure allows for the distillation of heat-sensitive compounds that might decompose at their normal boiling points. Understanding and controlling distillation temperatures are crucial in various scientific and industrial applications, including the purification of chemicals, the separation of petroleum fractions, and the production of alcoholic beverages. Different substances have distinct distillation temperatures, making it a valuable parameter for identification and separation purposes. For example, water boils at 100 degrees Celsius at standard atmospheric pressure, while ethanol boils at approximately 78.37 degrees Celsius.
