ABSTRACT

Liquid-Liquid Equilibria for the three ternary systems (dodecane + toluene + 1-ethyl-3-methylimidazolium methyl sulfate ([EMIM][MeSO4])), (dodecane + thiophene + [EMIM][MeSO4]) and (dodecane + pyridine + [EMIM][MeSO4]) were measured at 298.15 K and at atmospheric pressure. Experimental data were used to calculate the distribution coefficient and selectivity values. Results indicate that [EMIM][MeSO4] is a potential solvent for the extraction of pyridine from n-dodecane. It was found that NTRL and UNIQUAC models can used to represent with good accuracy ternary systems containing [EMIM][MeSO4]. Then, we have shown that [EMIM][MeSO4] can be used as solvent for the extraction of pyridine from a synthetic mixture.
