Abstract
The calculation of the viscosity of 51 multicomponent (48 ternary and 3 quaternary) nonelectrolyte liquid systems has been performed by means of a model based on Eyring's theory of viscous flow and the UNIQUAC equation. More than 1000 viscosity data points, under 0.1 MPa and in the temperature range of 283.15−323.15 K, have been calculated. The model is based on pure-component viscosities, pure-component molar volumes, and pure-component size and shape parameters, as well as two interaction parameters per binary system. The model binary interaction parameters were determined previously by correlation of experimental literature data on the viscosity of binary systems. A rather good agreement between experimental and calculated viscosities of ternary and quaternary liquid mixtures has been achieved. The overall mean relative standard deviation of the calculation is 2.95%. The results show that the model is adequate for estimating liquid mixture viscosities for different types of mixtures containing polar and nonpolar components.
