Excess volume, changes of refractive index and surface tension of binary 1,2-ethanediol + 1-propanol or 1-butanol mixtures at several temperatures

Abstract Excess molar volume, changes of refractive index, and surface tension deviations of binary mixtures of 1,2-ethanediol+1-propanol or 1-butanol have been determined at 293.15, 298.15, 303.15, and 308.15 K. The experimental data of refractive indices and surface tensions were compared with those predicted by different empirical expressions.
