Abstract: Knowledge of thermophysical properties of pure liquids and respective mixtures and their variation with temperatures are important for practical and theoretical purposes. The thermophysical properties of liquid mixtures are an invaluable data for the chemical engineer in the design and optimization of industrial processes. Studies on different thermophysical properties of liquid mixtures within wide range of composition and temperatures are valuable sources of information that may be used to examine the relation between the internal structure of the system and its physical properties. Though lot of work has been done in the case of pure liquids, data on thermophysical properties of liquid mixtures are not available in many systems. Hence the thermophysical properties of liquid mixtures have been studied for many binary liquid mixtures. In the present investigation therefore, thermophysical properties of the following binary liquid mixtures at 303.15 K, 313.15 K and 323.15 K have been determined. The excess values of thermophysical properties and thermoacoustical parameters of binary liquid mixtures are correlated using Redlich-Kister polynomial equation to obtain their coefficients and standard deviations. The interactions between the liquids in liquid mixtures under investigation are either strong specific type or weak dispersive type interactions. Redlich-Kister polynomial equation represented the excess molar volume, deviations of viscosity, refractive index and ultrasonic velocity which is indicated accurately well by percent standard deviation of less than three. Redlich-Kister polynomial equation represented the excess acoustical properties well which is indicated by percent standard deviations of less than three. Jouyban Acree viscosity model shows the percent standard deviation of lt 0.31. Jouyban Acree viscosity model holds good for the viscosity of binary liquid mixtures under investigation. newline newline newline
