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,
