Description 962-969
The thermo-physical parameters like density (ρ), ultrasonic velocity (u) and viscosity (η) have been experimentally measured
for the ternary liquid mixture of para-anisaldehyde (4-methoxy benzaldehyde) in n-Hexane solution with dimethylamine at
various temperatures such as 303 K, 308 K and 313 K and at fixed frequency of 2 MHz. The thermodynamic and acoustical
parameters such as adiabatic compressibility (β), internal pressure (πi), cohesive energy (CE), free volume (Vf), free length (Lf),
acoustic impedance (z), viscous relaxation time, Lennard Jones potential (LJP), and K value have been calculated from the
experimental data. The various excess properties including excess acoustic impedance (ZE), excess free length (𝐿􀯙
􀮾􁈻, excess
adiabatic compressibility (βE), excess free volume (Vf
E), excess ultrasonic velocity (UE) and excess internal pressure (πi
E) have
also been computed from the calculated values. The values of 𝑈􀮾, ZE, and 𝐿􀯙
􀮾 for each mixture have been fitted to the Redlich –
Kister polynomial equation. The variation of these parameters with respect to different concentration at different temperatures
for the ternary system of para-anisaldehyde + dimethylamine + n-hexane has been studied in accordance with their strength of
molecular interaction under the influence of ultrasonic wave of frequency 2 MHz.
