Experimental Investigation of Density & Refractive Index of Binary Liquid Mixtures of Tetrahydrofuran with Benzene, Methyl Benzene and Ethylbenzene at 308.15 K

Abstract

Densities and refractive index have been measured at 308.15 K over the entire composition range of binary mixtures of tetrahydrofuran withbenzene, methyl benzene, and ethyl benzene at 308.15 K. The measured data have been used to calculate the molar volume, molar refraction,excess refractive index, andexcess molar refraction, which are fitted to the Redlich-Kister polynomial equation. The results indicate the presenceof strong interactions between tetrahydrofuran with benzene, methyl benzene, and ethyl benzene. The deviations in excess refractive indicesvalues the follow the order THF + B < THF + MB < THF + EB. The results were discussed in terms of the existence of intermolecular interactions between the components in the liquid mixtures.
