Thermodynamic interactions in binary mixtures of 1-chloronaphthalene with n-alkanes

Thermodynamic interactions in binary mixtures of 1-chloronaphthalene with h exane, heptane, octane, nonane, decane, or dodecane have been studied using the experimental results of density and viscosity at 298.15, 303.1.5, 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-Patters on (PFP) and Flory theories. Deviations in logarithmic viscosity are calcul ated and compared with those obtained using the Bloomfield and Dewan equati on. From the speed of sound data, isentropic compressibilities have been ca lculated and compared with those calculated from the Benson and Kiyohara eq uation. The isothermal compressibilities calculated from the Benson and Kiy ohara equation have been compared with those calculated from the Flory equa tion of state. The excess volume, deviations in logarithmic viscosity, the deviations in internal pressure, deviations in free energy of activation, a nd isentropic compressibility have been fitted to the Redlich and Kister eq uation to derive the coefficients and standard errors.
