- Abstract
A semi-theoretical model based on the classical Eyring's mixture viscosity equation and the Wilson activity coefficient equation is presented for correlating the viscosity of ionic liquids with solvent systems. The accuracy of the proposed model was verified by comparing calculated and experimental vis- cosity values from the literature for 49 mixtures with a total of 1560 data points. The results show that the equation, similar to the Wilson activity coefficient equation, can be well applied to describe the non-ideal term in the Eyring's mixture viscosity equation. The model has a relatively simple mathematical form and can be easily incorporated into process simulation software.
