Abstract
Processes for separating an azeotropic mixture are provided. In an embodiment, such a process comprises exposing an azeotropic mixture comprising a first (hydro)fluorocarbon and a second (hydro)fluorocarbon to an ionic liquid comprising a cation and a non-fluorinated anion at a temperature and a pressure at which the ionic liquid absorbs more of one of the first and second (hydro)fluorocarbons than another of the first and second (hydro)fluorocarbons as determined on a mass basis to form a (hydro)fluorocarbon-containing ionic liquid and a processed azeotropic mixture.
