Özet

Excess molar volumes (VE) viscosities and refractive index have been evaluated for binary mixtures of glycerol + water, and glycerol + methanol at 298.15 K and 303.15 K. Excess molar volumes (VE) have been calculated from density. The excess molar volume (VE) results were fitted to the Redlich and Kister type polynomial equation to derive the binary coefficients and estimate the standard deviations between experimental and calculated results. It is observed that all mixtures show positive values of VE obviously due to increased physical interactions between glycerol and methanol, and water. © 2011 Chemical Society of Ethiopia.
