ABSTRACT

Dynamic viscosities, densities, and speeds of sound have been determined over the whole composition range for the binary systems cyclohexane (1) and cyclopentane (1) with acetone (2), butanone (2), or 2-pentanone (2) 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 compressibilities, deviations in isentropic compressibility, and viscosity deviations for the binary systems at the above-mentioned temperatures were calculated and fitted to the Redlich-Kister equation to determine the fitting parameters and the root-mean-square deviations. The UNIQUAC equation was used to correlate the experimental viscosity data. Predictions of the dynamic viscosities of this binary mixture from the UNIFAC-VISCO and ASOGVISCO methods have been determined.
