ABSTRACT

Densities, refractive indices, and volumetric heat capacities Cp/V have been measured at 298.15 K over the whole concentration range for the binary mixtures {tetrahydropyran + 2-pentanone, + 2-heptanone or + cyclopentanone}. From experimental data excess molar volumes, excess molar refractions, and excess molar isobaric heat capacities were calculated. Deviations of refractive index from ideality were determined by using a deviation function defined on a volume fraction basis. Excess molar enthalpies have been measured at the same temperature for the systems {tetrahydropyran + 2-pentanone, + 2-heptanone, + cyclopentanone or + cyclohexanone}. The discussion of these quantities entails a comparison with the results obtained in part 1 of this series for a homologous set of systems containing tetrahydrofuran.
