Thermo-acoustical Parameters Study in Binary Liquid Mixtures of Quinoline with Mesitylene at Temperatures T=(303.15, 308.15, 313.15 and 318.15)K

Ultrasonic velocities, densities, and viscosities have been measured in binary liquid mixtures of quinoline with mesitylene over the entire mole fraction range of quinoline at temperatures T=(303.15, 308.15, 313.15, and 318.15)K. From the experimentally measured data of ultrasonic velocity, density, and viscosity, thermo-acoustical parameters such as adiabatic compressibility (β), intermolecular free length (Lf), acoustical impedance (Z), and internal pressure (π) have been calculated in the binary liquid mixtures. These results have been explained in terms of intermolecular interactions between the components of the liquid mixtures. This study provides insight into the molecular interactions in binary liquid mixtures, which is crucial for understanding the physical properties and potential applications of such systems.
