Phase diagrams of binary systems containing tricyanomethanide-based ionic liquids and thiophene or pyridine-New experimental data and PC-SAFT modelling

Abstract : Isothermal vapor liquid equilibrium (VLE) phase diagram measurements for the binary systems composed of tricyanomethanide-based ionic liquids and thiophene or pyridine were carried out over the whole range of composition at temperature between (293.15 and 313.15) K using a static apparatus. Moreover, liquid liquid equilibrium (LLE) phase diagrams for the investigated systems have been determined at atmospheric pressure using a dynamic method. The impact of the cation core structure (imidazolium, or pyridinium, or pyrrolidinium) on the both VLE and LLE has been discussed. Modelling of the investigated properties in terms of molecular-based equation of state, namely perturbed-chain statistical associating fluid theory (PC-SAFT), was performed. Pure-fluid parameters for ionic liquids were obtained from ambient pressure densities and the Hildebrand solubility parameters. Calculations of VLE and LLE employed binary corrections to common combining rules fitted to experimental activity coefficients of thiophene and pyridine reported previously in literature.
