Liquid–liquid equilibria studies on ammonium and phosphonium based ionic liquid–aromatic–aliphatic component at T =298.15K and p =1bar: Correlations and a-priori predictions.

Highlights: [•] LLE of ammonium and phosphonium ionic liquids-aromatic-aliphatic component reported. [•] Experimental data were correlated with NRTL and UNIQUAC models. [•] Successful prediction using quantum chemical based COSMO-RS model. [•] Low cross contamination between both phases reported. [Copyright &y& Elsevier]
