Systems with ionic liquids: Measurement of VLE and γ∞ data and prediction of their thermodynamic behavior using original UNIFAC, mod. UNIFAC(Do) and COSMO-RS(Ol)

The new and the already available data for the various systems of imidazolium bis(trifluoromethylsulfonyl)imides [RR'IM][BTI] with alkanes, alkenes, cyclic hydrocarbons and alcohols were used to fit the required group interaction parameters for the group contribution methods original and mod. UNIFAC(Do). The predicted results were compared with the experimental data and the results using COSMO-RS(Ol).
