Viscosities and Excess Molar Volumes of Binary Mixtures of Propylene Carbonate with Tetrahydrofuran and Methanol at Different Temperatures

Densities and viscosities of the binary mixtures of propylene carbonate with methanol and tetrahydrofuran have been measured at (298.15, 308.15, and 318.15) K. The excess molar volumes and the deviations of the viscosity of the mixture from the ideal mole fraction rule have been calculated from these data. The computed results have been fitted to the Redlich−Kister polynomial relation to estimate the regression coefficients and standard errors for these systems.
