Ultrasonic Studie Of Thermo-Acoustic Parameters For Binary Liquid Mixtures Involving Triethylamine With N-Hexane At Different Temperatures

Abstract
-The ultrasonic velocity (u), density (ρ) and viscosity (η) have been measured for the binary mixtures of triethylamine with n-hexane at different temperature. From the experimental data, Adiabatic Compressibility (β), Free Length (Lf ), Free Volume (Vf)), Internal Pressure (i), Acoustic Impedance (Z), and Gibb’s free Energy(∆G) have been calculated. In addition to that the excess values of certain above parameters are also computed. These excess parameters have been used to discuss the presence of significant molecular interactions in binary mixture. By taking measurements at several concentrations of each liquid mixture, we obtained information about the molecular association between the two different molecules in the liquid mixture. The data presented may stimulate other researchers to consider the molecular processes taking place in these liquid mixtures. Keywords: Ultrasonic velocity, density, viscosity, thermo-acoustic parameters, intermolecular interactions.
