ABSTRACT
Gas liquid chromatography (g.l.c) was used to determine solute retention data for 33 solutes: (alkanes, alkenes, ketones, alcohols, alkynes, aromatic hydrocarbons, tetrahydrofuran, thiophene, acetonitrile and water) in new ionic liquid 2,3-dihydroxypropyl-N-methyl-2oxopyrrolidinium chloride [(OH)2 C3MPyr] [Cl]. This work was conducted in order to evaluate the ionic liquid (IL) for use as a potential extraction solvent for the organic compounds, and the assessment was based on the experimental activity coefficients at infinite dilution. The experiment was conducted at a series of four temperatures (313.15 to 343.15) K at 10 K intervals. The experimental data acquired over the investigated temperature range was then used to compute the thermodynamic functions at infinite dilution including partial molar excess enthalpies, E, , Gibbs free energy, E, as well as the entropy term, Tref E, 1 . From the results obtained, the intermolecular interactions of solutes with the chosen ionic liquid were discussed. This work provides insight about the nature of 2,3dihydroxypropyl-N-methyl-2-oxopyrrolidinium chloride ionic liquid, the effect of structure on thermodynamic properties, the influence of polar functional groups as well as choosing a suitable solvent for distinct separation difficulties. The selectivity and capacity values for some of the petrochemical extraction problems (heptane/thiophene, heptane/benzene, heptane/1-heptyne) were computed from 13 data and compared to the literature values with other ionic liquids. Evaluation of activity coefficients at infinite dilution provides a better understanding of the interactions occurring among the ionic liquid and the investigated compounds.
