Analysing Dielectric and Ultrasonic Studies of Liquid Mixtures

PHYSICS

The characteristics of liquid mixes are extremely relevant in thermodynamic, acoustic, and transport investigations. The compositional dependency of thermodynamic characteristics has shown to be a highly effective tool in understanding the type and extent of molecular aggregation caused by intermolecular interaction. This form of research is effective for characterising the many features of the physicochemical behaviour of liquid mixtures. Density (), viscosity (), and ultrasonic velocity (U) measurements were performed at 303, 308, and 313K for three ternary organic liquid mixes of 1-alkanols in binary mixtures of tetrahydrofuran (THF) and 1-chlorobutane (3:1) ratio. Acoustic characteristics such as adiabatic compressibility (β), free length (Lf), free volume (Vf), internal pressure (πi) and Gibb's free energy (∆G) have been computed using experimental data. The excess values of the aforementioned parameters, as well as the Grunberg-Nissan interaction parameter (d), have also been assessed and discussed in light of molecular interaction in the mixes.
