Example of a vapor-liquid phase diagram:
Liquid composition at a given temperature during the distillation process:
A pure liquid has a steady boiling point providing liquid and vapor are in equilibrium. In an easy distillation of a pure material, as the temperature mounts, the vapor pressure enhances. As the vapor increases, it exceeds out of the heated portion of the apparatus until it comes into contact with the icy exterior of the water-cooled condenser. Once the vapor is cooled, it compacts and passes along the condenser into the recipient.
Once a liquid blend is distilled the temperature of the refinement thermos will not stay steady except will slowly enlarge all through the distillation. Through a mixture of 2 liquids A and B, having steaming points TA and TB, and dissimilar vapor pressures, the vapor includes an advanced amount of the additional unstable section. The composition of the vapor in stability with a liquid blend is revealed in the Vapor-Liquid Phase Diagram.
