ABSTRACT

In this work, the dynamic viscosities, densities, and speed of sound for the binary mixtures, 2-pentanol with several alkanes (octane, decane, and dodecane), at 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 compresibility, deviations in isentropic compressibility, and viscosity 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. The UNIQUAC equation was used to correlate the experimental data. Predictions of the dynamic viscosities of these binary mixtures from UNIFAC-VISCO and ASOG-VISCO methods have been made. The interaction parameters within secondary alcohols with alkanes (OHs/CH2, OHs/CH3) have been determined for their application in the predictive UNIFAC-VISCO method.
