Viscosity of the binary systems 2-methyl-2-propanol with n-alkanes at T = (303.15, 308.15, 313.15, 318.15 and 323.15) K: Prediction and correlation – New UNIFAC–VISCO interaction parameters

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.
