As the distillation proceeds: • The liquid that distills (the distillate) is enriched in the lower boiling component (in this case A). • The liquid left behind (in the pot) is enriched in the higher boiling component (in this case B). • The temperature of the liquid distilling increases over time.

Distillation Distillation is a commonly used method for purifying liquids and separating mixtures of liquids into their individual components. Familiar examples include the distillation of crude fermentation broths into alcoholic spirits such as gin and vodka, and the fractionation of crude oil into useful products such as gasoline and heating oil.

Jan 01, 2011 Short-path distillation is a process where volatile components can be rapidly vaporized at a wide range of temperatures in a very short time due to high vacuum used. Vacuum can be of the order of 10 −4 to 10 −6 bar at which volatility of most compounds becomes so high that it can allow operating at lower temperatures.

Jul 13, 2021 Short path distillation is a method used to purify relatively small volumes because the shorter the distance they need to travel the less material is lost on the walls of the apparatus. Much like alcohol distillation, we will have our heads, which are the most volatile fraction with the lowest boiling points.

Sep 01, 2003 Short path distillationSPD is commonly used to separate or recover low volatility or heat labile components from liquid mixtures. It is typically used to fractionate waxes since an SPD unit can operate at very low pressures (0.1–10 Pa)—much lower than is possible in standard vacuum distillation units.
