Phase Behaviour of Ionic Liquid Systems with Azeotropic Organic Mixtures

4 Phase Behaviour of Ionic Liquid Systems with Azeotropic Organic Mixtures 

Other azeotropic organic mixtures that can be separated by using ionic liquids as entrainers include (alkane + ester), (cycloalkane + ketone) and (benzene + hexafluorobenzene). Especially the effect of the ionic liquid on the last-mentioned mixture is interesting. The binary (benzene + hexafluorobenzene) is known to have double azeotropes that is, a minimum pressure and a
