Thermodynamic Properties of Binary Mixtures of Tetrahydropyran with Anilines at 308.15 K

Abstract

Excess molar volumes, V E , excess molar enthalpies, H E , speeds of sound, u, and vapor-liquid equilibrium data of tetrahydropyran (1) + aniline or N-methylaniline or 2-methylaniline (2) binary mixtures have been measured over the entire mole fraction range at 308.15 K. Speeds of sound and vapor-liquid equilibrium data have been utilized to predict isentropic compressibility changes of mixing, κ S E

Excess Heat Capacities for Lactam + Chlorotoluene Binary Mixtures

“…This paper reports C P E data of pyrrolidin-2-one or 1-methylpyrrolidin-2-one (1) + o -, m -, or p -chlorotoluene (2) binary mixtures at 293.15 K, 298.15 K and 303.15 K. A literature survey showed that C P E data of these mixtures are not reported in the literature. Graph theory (which in turn deals with constituent of mixtures) has been successfully employed to determine excess molar volumes, V E , excess molar enthalpies, H E , excess Gibbs free energies, G E , and excess isentropic compressibilities, κ S E data of liquid mixtures. − In this study, a connectivity parameter of the third degree of a molecule, 3 ξ which in turn deals with topology of a molecule (Graph theory) has been utilized to predict C P E data of the investigated mixtures.…”

Thermodynamic properties of binary mixtures of tetrahydropyran with pyridine and isomeric picolines: Excess molar volumes, excess molar enthalpies and excess isentropic compressibilities

“…This has greatly stimulated the need for extensive information about thermodynamic properties of mixtures containing cyclic ether. In our systematic investigations of thermodynamic properties of binary and ternary mixtures containing cyclic ether, excess molar volumes, V E , excess molar enthalpies, H E , excess Gibbs free energies, G E and excess isentropic compressibilities, Ä E S data of binary [1][2][3] and ternary [4,5] mixtures have been analyzed in terms of Graph theory (which involves the topology of a molecule). In continuing with our study on thermodynamic properties of cyclic mixtures, we report here the densities, speeds of sound and excess…”
