A heteroazeotrope is an azeotrope where the vapour phase coexists with two liquid phases. Sketch of a T-x/y equilibrium curve of a typical heteroazeotropic mixture == Examples of heteroazeotropes == Benzene - Water NBP 69.2 °C Dichloromethane - Water NBP 38.5 °C n-Butanol - Water NBP 93.5 °C Toluene - Water NBP 82 °C == Continuous heteroazeotropic distillation == Heterogeneous distillation means that during the distillation the liquid phase of the mixture is immiscible.
