The mutual transformations of the structures of vapor–liquid equilibrium diagrams of ternary systems containing zeotropic, monoazeotropic, and biazeotropic binary components via the formation of a binary internal tangential azeotrope in the case of varying external conditions are considered. The characteristic features of the appearance of binary biazeotropy in ternary systems belonging to different types of structures of vapor–liquid equilibrium diagrams are found. The mutual transformation of vapor–liquid phase diagrams of systems of classes 3.0.0-1 and 3.[2.0.0].0-2a is illustrated via a computational experiment using an isobutyl acetate–acetic acid–sulfolane system as an example.
