Molecular interaction studies in binary mixtures of tetrahydrofuran with arene-substituted alcohols: acoustic and volumetric study

Abstract

ABSTRACTIn the present investigation, density and speed of sound have been reported for binary liquid mixtures of tetrahydrofuran with benzyl alcohol and 4-methoxybenzyl alcohol over the entire composition range at T = 303.15, 308.15 and 313.15 K. From the experimental data, excess molar volume (), excess isentropic compressibility (), excess molar isentropic compressibility (), and excess speed of sound () of liquid mixtures have been calculated. The excess partial molar volume,, , excess partial molar isentropic compressibility, , over the whole composition range together with partial molar volume,, , partial molar isentropic compressibility ,, excess partial molar volume,, , and excess partial molar isentropic compressibility, , at infinite dilution have also been calculated. All excess properties have been correlated using Redlich–Kister smoothing polynomial equation.
