Study of Acoustic Parameters of Binary Mixtures of Cyclohexane with 2-Methoxyethanol

The interactions existing between components of the binary mixtures, namely cyclohexane and 2-methoxyethanol are found to be affected by the ultrasonic wave with a frequency of 2 MHz. Using the experimental data, some thermodynamic and acoustic parameters are computed at different temperatures over the entire composition range. Among the parameters are intermolecular free length (L-f), free volume (V-f), relaxation time (tau), acoustic impedance (Z), Rao's constant (R) and Wada's constant (W). Variations in these parameters at different concentrations of the components are non-linear and are explained based on structural changes taking place in the solutions. Variations in all the parameters play a significant role in arriving at the possible interactions existing between solute and solvent.
