Abstract:Ionic Liquids have been identified as one of the new classes of solvents that offer opportunities to transform traditional chemical processes into clean, green technologies. Capacity and selectivity at infinite dilution activity coefficients of 1508 ILs have been computed by COSMOtherm for the extraction of toluene from toluene-heptane mixture at 1 atm and 40°C. Some potential ILs are screened computationally for the whole composition range. A good number of ionic liquids are found that display considerably higher capacity and higher selectivity than those of sulfolane which is the most popular solvent in aromatic extraction. A general trend is found in the qualitative relationship between capacity and selectivity---when one is high, the other is low and vice versa. To obtain a good compromise between capacity and selectivity, an attempt is made to tailor new IL based solvents by mixing two suitable ILs in specific proportion. COSMO therm predicts the behavior of binary IL solvents as ideal, synergistic and anti-synergistic. (Abstract shortened by UMI.)
