At the previous case the binary system forms already a heterogeneous azeotrope. The other application of the heteroazeotropic distillation is the separation of a binary system (A-B) forming a homogeneous azeotrope.

WebIt is observed that water forms a heterogeneous azeotrope with isobutyl acetate and a 2-phase region is present in the diagram. The water - isobutyl acetate azeotrope is an unstable node, while the acetic acid is a stable node [4]. Based on the diagram, a separation method using two distillation columns and a decanter is proposed.
