Ultrasonic velocity, density and viscosity of solutions of some binary mixtures of meta amino phenol in dioxane, methanol and acetonitrile were measured at 303 K. From these experimental data, various acoustical properties such as adiabatic compressibility (b), intermolecular free length (Lf ), free volume (Vf), internal pressure (pi), acoustic impedance (Z), molar sound velocity (R) and molar compressibility (W) were calculated. The results are interpreted in terms of molecular interactions occurring in the solutions.
