Thermodynamic interactions in binary mixtures of 1-chloronaphthalene with <i>n</i>-alkanes

Abstract

Thermodynamic interactions in binary mixtures of 1-chloronaphthalene with hexane, heptane, octane, nonane, decane, or dodecane have been studied using the experimental results of density and viscosity at 298.15, 303.15, and 308.15 K as well as speed of sound measurements at 298.15 K over the entire mole fraction range. From the density data, excess molar volumes have been calculated and compared with those calculated from Prigogine-Flory-Patterson (PFP) and Flory theories. Deviations in logarithmic viscosity are calculated and compared with those obtained using the Bloomfield and Dewan equation. From the speed of sound data, isentropic compressibilities have been calculated and compared with those calculated from the Benson and Kiyohara equation. The isothermal compressibilities calculated from the Benson and Kiyohara equation have been compared with those calculated from the Flory equation of state. The excess volume, deviations in logarithmic viscosity, the deviations in internal pressure, deviations in free energy of activation, and isentropic compressibility have been fitted to the Redlich and Kister equation to derive the coefficients and standard errors.
