Thermodynamic properties for binary mixtures of 1-chlorohexane plus some hydrocarbons at different temperatures and atmospheric pressure

The values of densities and speeds of sound for the binary mixtures of 1-chorohexane with two hydrocarbons, as toluene and tetradecane, were measured at several temperatures in the range of (298.15 to 318.15) K and atmospheric pressure. The obtained experimental data of the mixture were correlated by the Jouyban-Acree model. From the experimental data, the related excess and deviation quantities, namely the excess molar volumes, the partial molar volumes, the excess speeds of sound, the isentropic compressibilities, the excess isentropic compressibilities, the molar isentropic compressibilities and the excess molar isentropic compressibilities, were calculated and reported in this work. All these excess thermodynamic properties were correlated with the Redlich-Kister polynomial equation. The experimental results have been also used to test the applicability of the Prigogine-Flory-Patterson theory. Discussions concerning the experimental and calculated results in relation to the molecular interactions and structural effects between components of mixtures are presented. (C) 2019 Elsevier B.V.
