Thermodynamic interactions in binary mixtures of 1-chloronaphthalene and monocyclic aromatics

Thermodynamic interactions in binary mixtures of 1-chloronaphthalene with t he monocyclic aromatics have been studied through calculation of excess mol ar volumes from Flory equation of state and that of Prigogine-Flory-Patters on theories using the experimental results of density, viscosity and speed of sound. The experimental excess viscosity has been compared with Bloomfie ld-Dewan theory, while the excess isentropic and isothermal compressibiliti es have been analysed using Benson-Kiyohara theory. Efforts have also been made to calculate the excess internal pressure from Prigogine-Saraga theory . All the excess quantities have been fitted to Redlich-Kister equation to estimate the binary coefficients and standard deviations.
