Fractional Distillation of Air and Other Demonstrations with Condensed Gases  Maria Oliver-Hoyo and William L. Switzer, III
This demonstration builds upon the commonly performed liquefaction of air not only to show the presence of nitrogen and oxygen, but also the presence of two other components, carbon dioxide and water. Several extensions are suggested: one to show boiling point elevation in solution and another to show the elevation of both boiling point and sublimation point with pressure. No special apparatus is required permitting presentations to audiences in a variety of settings. These demonstrations give the opportunity to discuss properties of gases, solution chemistry, and phase equilibria.

An Analogy between Fractional Distillation and Separating Physically Fit and Physically Less Fit Persons  Doble Mukesh
Separating two liquids in a fractional distillation column on the basis of their difference in boiling points is analogous to separating a group of people on the basis of their physical fitness by making them climb a flight of stairs.

Basic Laboratory Chemistry  reviewed by Deborah McCool
Basic Laboratory Chemistry is a series of sixteen programs presenting demonstrations of many processes and experimental techniques used in the chemistry laboratory in both macroscale and microscale. Topics included in the programs are assembling macroscale and microscale apparatus, spectroscopy, chromatography, and procedures such as filtration, extraction, distillation, and titration.

Teaching Distillation Knowledge: A Video Film about Distillation Bridging a Gap Between Theory and Practice  Martin J. Goedhart, Hanno van Keulen, Theo M. Mulder, Adri H. Verdonk, and Wobbe De Vos
The authors observed that first year students hardly used their knowledge of phase theory in the design and performance of distillations. They therefore developed a video in which they confront students with the boiling properties of liquid mixtures.
