INVESTIGATING VISCOSITY AND EXCESS THERMODYNAMIC PROPERTIES IN BINARY MIXTURES OF CYCLIC ETHER AND 1-ALKANOLS AT 303.15K

Abstract

The ultrasonic study of liquid mixtures has emerged as a crucial tool for unraveling the intricacies of molecular interactions and elucidating the physicochemical behavior of these systems. Over the past three decades, researchers have harnessed this approach to delve into the thermodynamic and transport properties of liquid mixtures, which has not only provided insights into their deviation from ideal behavior but has also shed light on the intermolecular interactions within these complex systems. In particular, excess thermodynamic functions have played a pivotal role in this endeavor, demonstrating their sensitivity to variations in both intermolecular forces and molecular size. Fundamental properties such as internal pressure and free volume, originally explored by Hildebrand and Scott, have been instrumental in the investigation of molecular interactions within binary liquid mixtures. Additionally, the measurement of ultrasonic velocity, viscosity, and density has proven to be indispensable in comprehending the molecular intricacies inherent in liquid mixtures. This comprehensive utilization of thermodynamic and transport properties not only enhances our understanding of real liquid mixture behavior but also allows for a deeper exploration of the structural transformations occurring within these complex systems.
