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

ABSTRACT

In 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 ($V_m^E$), excess isentropic compressibility (${\kappa }_s^E$), excess molar isentropic compressibility (${\kappa }_{s,m}^E$), and excess speed of sound ($u^E$) of liquid mixtures have been calculated. The excess partial molar volume,${\bar{V}}_{m,1}^E$, ${\bar{V}}_{m,2}^E$, excess partial molar isentropic compressibility, ${\bar{K}}_{s,m,1}^E$${\bar{K}}_{s,m,2}^E$, over the whole composition range together with partial molar volume,${\bar{V}}_{m,1}^0$, ${\bar{V}}_{m,2}^0$, partial molar isentropic compressibility ${\bar{K}}_{s,m,1}^0$,${\bar{K}}_{s,m,2}^0$, excess partial molar volume,${\bar{V}}_{m,1}^{0E}$, ${\bar{V}}_{m,2}^{0E}$, and excess partial molar isentropic compressibility, ${\bar{K}}_{s,m,1}^{0E}$,${\bar{K}}_{s,m,2}^{0E}$ at infinite dilution have also been calculated. All excess properties have been correlated using Redlich–Kister smoothing polynomial equation.
