ABSTRACT
Ternary (liquid+liquid) equilibrium data are presented for mixtures of 1-hexyl-3-methylimidazolium (tetrafluoroborate or hexafluorophosphate)+benzene+(heptane or dodecane or hexadecane) at T = 298.2K.The tie line compositions of the conjugate solutionswere obtained by means of density measurements and a standard density calibration curve. Large regions of immiscibility (increasing in the order of hexadecane>dodecane>heptane) and favourable skewing of the tie lines towards the solvent axis provide indications of the favourable use of the ionic liquids in solvent extraction. Selectivity values computedfromthe experimentaldata confirmthis.Correlation of the experimental tie lines was conducted through the use of theNTRLequation,which provides good correlationof the experimental data.
