EXCESS PROPERTIES 8 THEORETICAL ASSESSMENT OF ULTRASONIC STUDIES OF TERNARY LIQUID MIXTURES OF 2-BROMOANISOLE + 1-BUTANOL + n-HEXANE AT DIFFERENT TEMPERATURES

Abstract

Excess properties like Excess Adiabatic Compressibility (βE), Excess Free Length (Lf E), Excess Free Volume (Vf E), Excess Internal Pressure (πi E), Excess Ultrasonic Velocity (UE) and Excess Acoustic Impedance (ZE) along with molecular interaction parameter and formation constant have been evaluated from the measured values of Ultrasonic Velocity (U), Density (ρ) and Viscosity (η) for a ternary liquid system consisting of 2-Bromoanisole + 1-Butanol in n- Hexane solvent at 303, 308 8 313K at a frequency of 2MHz. The excess properties have been used to discuss and to establish the presence of significant molecular interaction in terms of dipole-dipole, dipole induced-dipole, charge transfer, hydrogen bonded and donor acceptor interactions. The ultrasonic velocity is calculated according to Namoto’ s relation, Ideal Mix Relation, Impedance Dependent Relation and Junjies Relation theories and compared with the experimental values and to validate the experimental values with suitable theory for the ternary liquid mixtures containing 2-Bromoanisole +1- Butanol in n-Hexane solvent at 303,308 8 313K.
