COSMO-UNIFAC model for ionic liquids

The united chemical thermodynamic model, that is, COSMO-UNIFAC model was first extended to the systems containing ionic liquids (ILs). This model for ILs combines the respective advantages of COSMO-based (priori prediction) and UNIFAC (relatively accurate prediction) models. The comparison of the predicted values by COSMO-UNIFAC model with experimental data indicates that this model can provide a moderate quantitative prediction for the systems containing ILs when the UNIFAC model parameters are vacant.
