Abstract

Viscosities of ten binary liquid mixtures consisting of ionic liquids and organic compounds, determined at atmospheric pressure and in a wide temperature range, were calculated using two different approaches, predictive by group contribution models (UNIFAC-VISCO and ASOG-VISCO) and correlative (Seddon, Grunberg–Nissan, McAlister, Eyring-UNIQUAC and Eyring-NRTL models), and compared using literature data. The obtained results were analysed in terms of the applied approach and model. For UNIFAC-VISCO and ASOG-VISCO predictive models, the literature viscosity data were used to determine new interaction parameters.
