Abstract
Isentropic compressibilities κS, excess isentropic compressibilities κSE, excess molar volumes VE, viscosity deviations Îη, and excess Gibbs energy of activation of viscous flow ÎG*E for nine binary mixtures of C4H8O with CCl4, CHCl3, CHCl2CHCl2, 1-C6H13Cl, 1-C6H13Br, CH3CO2CH3, CH3CO2C2H5, CH3CO2C4H9, and CH3CO2C5H11 at 303.15 K have been derived from experimental densities Ï, speeds of sound u, refractive indexes nD and viscosities η. The limiting values of excess partial molar volumes of C4H8O at infinite dilution V1E,â in different solvents have been estimated. The results obtained for dynamic viscosity of binary mixtures were used to test the semi-empirical relations of Grunberg-Nissan, Tamura-Kurata, Hind-McLaughlin-Ubbelohde, Katti-Chaudhri, McAllister, Heric, and Auslaender. Finally, the experimental refractive indexes were compared with the predicted results for Lorentz-Lorenz, Dale-Gladstone, Eykman, Arago-Boit, Newton, Oster, Heller, and Wiener equations.
