Thermodynamic and topological analysis of the formation of internal tangential azeotropes in binary two-phase systems
The analysis of properties of the internal tangential azeotrope that leads to biazeotropy as a result of the bifurcation was carried. Internal tangential azeotrope has a number of specific properties, some of which is identical to usual binary azeotropes, and the other part of properties has certain...

| description | The analysis of properties of the internal tangential azeotrope that leads to biazeotropy as a result of the bifurcation was carried. Internal tangential azeotrope has a number of specific properties, some of which is identical to usual binary azeotropes, and the other part of properties has certain characteristics peculiar only to this type of singular points. There was considered the evolution of binary zeotropic mixture to binary biazeotropic mixture in two ways: through the formation of boundary tangential azeotropes and through the formation of internal tangential azeotropes (ITA). As the mathematical model for description of basic properties of ITA van der Waals equation was used. To describe additional properties the analysis of ITA in terms of excess thermodynamic functions was carried. |
