Abstract
Liquid + liquid equilibrium data for (1-ethyl-3-methyl imidazolium ethyl sulfate + thiophene + 2,2,4-trimethylpentane) and (1-ethyl-3-methyl imidazolium ethyl sulfate + thiophene + toluene) have been determined at 298.15 K and atmospheric pressure. The ionic liquid has a great capacity to dissolve not only thiophene but also the toluene, being practically immiscible with 2,2,4-trimethylpentane. Equilibrium data of systems with toluene have been fairly well correlated with the NRTL and UNIQUAC equations but for the system with 2,2,4-trimethylpentane high deviations have been found with both equations.
