  Abstract:  Ultrasonic propagation velocity, density, dynamic viscosity coefficient and thermal expansion coefficient measurements were carried out un the binary liquid system dichloromethane – benzene for the pure components and for different dichloromethane concentrations at different temperatures in the range 283 – 303 K. Based on the experimental data quantities as: the adiabatic compressibility coefficient, the available volume, the ay force parameter, the free volume were calculated. A comparison between different internal pressure formulas, in connection with the ultrasonic propagation velocity as a common parameter is made. The obtained results give information about the contribution of different types of interactions to the overall effect of molecular interaction in the studied system and about their dependence on the dichloromethane concentration and the temperature of the mixture.
