Distillation separates chemicals by the difference in how easily they vaporize.
The two major types of classical distillation include continuous distillation and batch distillation. Continuous distillation, as the name says, continuously takes a feed and separates it into two or more products. Historical Background Distillation has been around for a long time. Earliest references are to Maria the Jewess who invented many types of stills and reflux condensers. Common Middle Ages and Renaissance uses of distillation included the manufacture of brandy and other spirits from wine.
