Viscosities, densities and speed of sound have been measured over the whole composition range for (2-propanol with octane, or decane, or dodecane) at T= (293.15, 298.15, and 303.15) K and atmospheric pressure along with the properties of the pure components. Excess molar volumes, isentropic compressibility, deviations in isentropic compressibility and viscosity deviations 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-meansquare deviations. Prediction of the dynamic viscosities of this binary mixture from UNI-FAC-VISCO and ASOG-VISCO methods has been determined. (C) 2003 Elsevier Science Ltd. All rights reserved.
