ABSTRACT

Viscosities for the binary mixtures 2-methyl-2-propanol+n-heptane, +n-octane, +n-nonane and +n-decane have been measured at 303.15, 308.15, 313.15, 318.15 and 323.15 K and atmospheric pressure. Viscosity deviations for the binary systems were fitted to the Redlich-Kister polynomial equation. The UNIFAC-VISCO and the ASOG-VISCO methods were used to predict the dynamic viscosities of binary mixtures. The viscosity data have also been correlated by Teja-Rice and McAllister models. In addition, the experimental values of viscosity were used to determine the new interaction parameters of alkanes with tertiary alcohols (CH3/OHt and CH2/OHt) for their application in the UNIFAC-VISCO model.
