Ultrasonic Study of Molecular Interaction in Binary Liquid Mixture Triethylamine in Benzene at 301.15K

The Ultrasonic velocity, density, and viscosity have been measured for binary mixture of triethylamine (TEA) and benzene at four different temperatures for a constant frequency (5 MHz). These experimental data have been used to estimate the thermodynamic parameters such as ultrasonic velocity (u), viscosity (ƞ), density (ρ), excess adiabatic compressibility (β_a^E), excess free length (L_f), excess free volume (V_f), excess viscosity (η^E), excess acoustic impedance (Z^E) for the solution. The excess values of the parameters are also evaluated and discussed.
