Densities, speeds of sound and viscosities of binary liquid mixtures of octan-2-ol with benzene and halobenzenes at 298.15 and 303.15 K

Abstract

Densities ρ, speeds of sound u, viscosities η and refractive indices n D of binary mixtures of octan-2-ol with benzene, chlorobenzene and bromobenzene have been measured over the entire range of composition at 298.15 and 303.15 K and atmospheric pressure. From the experimental data, excess molar volumes V E , isentropic compressibilities κ S , excess isentropic compressibilities κ S E , and deviations of speeds of sound u D , have been calculated at 298.15 and 303.15 K. These excess functions have been fitted to the Redlich–Kister polynomial equation. The viscosity data have been correlated using Kendall–Monroe, Grunberg–Nissan, Tamura–Kurata, Hind–Mclaughlin Ubbelohde and Katti–Chaudhary viscosity models, and McAllister's three-body interaction model at different temperatures.
