Binary and ternary (liquid + liquid) equilibrium for {methylcyclohexane (1) + toluene (2) + 1-hexyl-3-methylimidazolium tetracyanoborate (3)/1-butyl-3-methylimidazolium tetracyanoborate (3)}

► Binary and ternary extractions for two ionic liquids with organic compounds were measured. ► NRTL and UNIQUAC thermodynamic models were used to fit the experimental data. ► UNIQUAC model gives better predictions than the NRTL model. ► Ionic liquids showed interesting properties as solvents to be applied in separation processes.
