| Abstract |
Sulfolane, an ionic liquid, and a eutectic solvent are used as an extractable solvent in order to separate aromatic compounds, which are synthetic raw materials for petrochemical products, from hydrocarbon mixtures. In particular, eutectic solvents are environmentally friendly, and are clean solvents with many merits in the separation process because they are easy to manufacture. The synthesized eutectic solvent was composed of Methyltriphenylphosphonium(HBA) bromide and several other hydrogen bond donors(HBD). The cloud point of the binary system was analyzed to compare the affinity of the eutectic solvent for toluene and heptane. All samples for securing LLE data for the ternary system were prepared by mixing toluene, heptane, and eutectic solvents at different specific molar ratios. The prepared sample was sealed in a 20 ml vial, stirred for 3 hours, and subjected to a liquid-liquid phase behavior test at 20 ℃ and 40 ℃ in a water bath. Samples were separated into two phases under all conditions, and the compositions of the toluene and heptane for each phase were analyzed by using 300 Hz 1H-NMR. The triangulation is drawn using the obtained experimental data and the partition coefficient and selectivity are calculated from the tie-line data obtained from the experiment.
