ABSTRACT

The dynamic viscosities, densities, and speed of sound for the binary mixtures (2-butanol with octane, or decane, or dodecane) at several temperatures T=(293.15, 298.15, 303.15) K have been measured over the whole composition range and atmospheric pressure along with the properties of the pure components. Excess molar volumes, isentropic compressibility, deviations in isentropic compressibility, and viscosity deviation for the binary systems at the above-mentioned temperatures were calculated and fitted to Redlich-Kister equation to determine the fitting parameters and the root-mean-square deviations. UNIQUAC equation were used to correlate the experimental viscosity data. UNIFAC-VISCO method and ASOG-VISCO method, based on contribution groups, were used to predict the dynamic viscosities of the binary mixtures.
