Studies of some acoustical properties in binary solutions

Various acoustical properties such as isentropic compressibility, specific impedance, molar sound velocity, molar compressibility, van der Waals constant, intermolecular free length, excess molar volume (VE), excess viscosity, excess adiabatic compressibility, Gibb’s free energy of activation for viscous flow etc. have been calculated in three binary systems: anisole+methanol, anisole+chloroform and anisole+dimethyl foramide from sound velocity (2 MHz), density and viscosity measurements at 30°C. The results are interpreted in terms of molecular interactions occurring in the solutions.
