Measurements and Modeling of Physicochemical Properties of Pure and Binary Mixtures Containing 1,2-Dimethoxyethane and Some Alcohols

In this paper, experimental values of densities, speeds of sound, and refractive indices in a temperature range of 293.15-323.15 K have been measured as a function of composition for the binary liquid mixtures of 1,2-dimethoxyethane with alcohols such as methanol, propan-1-ol, propan-2-ol, and butan-2-ol. From these experimental values, excess/derived properties such as excess molar volume, isentropic compressibility, deviation in isentropic compressibility, and deviation in the refractive index have been calculated. Excess/derived properties have been correlated using the Redlich-Kister equation and physicochemical properties modeled using the cubic plus association equation of state for pure and binary mixtures. The results are interpreted with respect to possible molecular interactions between components.
