🔬 Introduction to Vacuum Distillation

Vacuum distillation, also known as distillation under reduced pressure, is a type of distillation that allows for the purification of compounds that are not readily distilled at ambient pressures. This technique is used to separate compounds based on differences in their boiling points, as explained in the Chemical Engineering field. The boiling point of a compound is a critical factor in distillation, and vacuum distillation enables the purification of compounds that would otherwise decompose or be difficult to distill at ambient pressures. For instance, Distillation is a common unit operation in many chemical plants, and vacuum distillation is a specialized technique used to optimize the distillation process. The Clausius-Clapeyron relation is a fundamental concept in thermodynamics that helps calculate the reduction in boiling point of compounds under reduced pressure.

💡 History of Vacuum Distillation
