One variety of this process uses a short-path apparatus known as a Kugelrohr. The Fenske equation is used in another form of this process to determine the necessary number of theoretical plates. Raoult's law is used in one variety of this process to manipulate the vapor pressure of the substance involved in this technique. Azeotropes are mixtures of liquids that can not be separated using the fractional form of this technique, in which the more volatile compound has a higher concentration in the produced vapor. For 10 points, name this laboratory technique of separating liquid mixtures based on their boiling points.
