“…In other words, structural contributions arising from geometrical fitting of one component into the other because of differences in the free volume and molar volume between components lead to a overall negative contribution to V m E . Here in the present mixtures, it may be concluded that the chemical or specific intermolecular interactions dominate over the other types of interactions [23,24].…”

Speeds of sound, u i jk , of tetrahydropyran (THP) (i) + benzene ( j) + toluene or o-or p-xylene (k), and tetrahydropyran (i) + toluene ( j) + o-or p-xylene (k) ternary mixtures have been measured over the entire mole fraction range at 308.15 K and atmospheric pressure. The speed-of-sound data have been used to calculate isentropic compressibilities, (κ S ) i jk , and excess isentropic compressibilities,jk values for the investigated mixtures are correlated with the RedlichKister equation to estimate ternary adjustable parameters and standard deviations. The Moelwyn-Huggins concept (Huggins, Polymer 12:357, 1971) of interaction between the surfaces of components of binary mixtures has been extended to predict excess isentropic compressibilities of ternary mixtures by employing the concept of connectivity parameters of the third degree of a molecule (which in turn depends on its topology). It has been observed that (κ S ) i jk values predicted by the MoelwynHuggins concept compare well with corresponding experimental values.

“…The thermodynamic properties of liquid mixtures are required to improve the various parameters involved in thermodynamic models. Our research group is carrying out a research project on thermodynamic and topological characterization of multicomponent mixtures containing cyclic ether as an oxygenated additive − with organic solvent with the purpose of providing thermodynamic data and testing of thermodynamic models for the solutions. A literature survey showed that no data on thermodynamic properties for the mixtures of o -chlorotoluene (1) + 1,3-dioxolane or 1,4-dioxane or tetrahydropyran (2) were reported.…”

The densities, ρ, speeds of sound, u, and excess heat capacities, C P E data of binary mixtures formed by o-chlorotoluene with 1,3-dioxolane or 1,4-dioxane or tetrahydropyran at (298.15, 303.15, and 308.15) K and excess molar enthalpies, H E , of the same mixtures at 308.15 K have been measured over the entire composition range at atmospheric pressure. The excess molar volumes, V E , and excess molar isentropic compressibilities, κ S E , data have been calculated from experimental densities and speeds of sound data. The V E , κ S E , and H E values for o-chlorotoluene (1) + 1,3-dioxolane or 1,4-dioxane (2) mixtures are positive, and those for o-chlorotoluene (1) + tetrahydropyran (2) mixture are negative over whole range of composition. However, C P E values for the studied mixtures are positive over the entire range of composition. The V E , κ S E , H E , and C P E data have been estimated in terms of graph and Prigogine−Flory−Patterson (except C P E data) theories. The results indicate that V E , κ S E , H E , and C P E values estimated via graph theory are in agreement with experimental values.
