Thermodynamic Study of Properties in Certain Binary Liquid Mixtures Containing Anisole with 2-Butoxyethanol at Different Temperatures (303.15K to 318.15K)

Abstract

Comprehensive experimental investigations were carried out on density (ρ), viscosity (η), and ultrasonic velocity (u) for binary mixtures comprising Anisole and 2-Butoxyethanol within the temperature range of 303.15K to 318.15K, covering the complete range of mole fractions. These parameters were measured at intervals of 5K. Derived excess parameters, including acoustic impedance (ZE), intermolecular free length (LEf), molar volume (VEm), excess ultrasonic velocity (uE), and excess viscosity (ηE), were calculated to probe the molecular interactions present in the mixture. These excess parameters were correlated with temperature and mole fraction, revealing the complexity and nature of intermolecular interactions. Notably, the Arrhenius, Bingham, Eyring, Grunberg, Kurata, Nissan, and Tamura models were utilized to theoretically validate the acquired empirical data. This study aims to offer invaluable insights into the thermodynamics and molecular dynamics that govern these binary liquid mixtures.
