Abstract

Refractive indices and molar volume of binary liquid mixture of 1, 4-dioxane with 1-butanol were measured over the entire composition range at T= (298.15, 303.15, 308.15, 313.15 & 318) K using Anton Paar and Abbemat Refractometer. Basing empirical formulae and the measured data were utilized to evaluate the molar refraction (Rm), molecular radii (r), internal pressure (pi) along with their excess parameters. The computed results of RmE, rE and piE were fitted to the Redlich–Kister polynomial equation and focused on the molecular interactions present in the mixture.

Keywords: Refractive Indices, Molar Refraction, Molecular Radii, Internal Pressure, 1,4-Dioxane, 1-Butanol, Binary Mixtures
