Excess Molar Volumes and Viscosities of Binary Mixtures of Sulfolane with Benzene, Toluene, Ethylbenzene, <i>p</i>-Xylene, <i>o</i>-Xylene, and <i>m</i>-Xylene at 303.15 and 323.15 K and Atmospheric Pressure

Abstract

Experimental data on density and viscosity at 303.15 and 323.15 K are presented for the binary mixtures of sulfolane + benzene, toluene, ethylbenzene, p-xylene, o-xylene, and m-xylene. From these data, excess molar volumes and deviations in viscosity have been calculated. The computed quantities have been fitted to the Redlich−Kister equation to derive the coefficients and estimate the standard error values. The results are discussed in terms of the intermolecular interactions.
