Thermodynamic properties of binary mixtures containing tetrahydropyran: Excess molar volumes, excess molar enthalpies and isentropic compressibilities changes of mixing
چکیده انگلیسی
Excess molar volumes, VE, excess molar enthalpies, HE and speeds of sound, u data of tetrahydropyran (i) + cyclohexane or n-hexane or n-heptane (j) binary mixtures have been measured using dilatometer, calorimeter and interferometer over whole mole fraction range at 308.15 K. Speeds of sound data have been utilized to predict isentropic compressibilities changes of mixing, κSE. The analysis of VE in terms of Graph theory reveals that (i + j) mixtures are characterized by dipole-induced dipole interactions between THP and cyclo or n-alkanes to form 1:1 molecular complex. HE and κSE data of the investigated mixtures have also been analyzed in terms of Graph theory. VE, HE and κSE data predicted by Graph theory compare well with their corresponding experimental values.
