Why are aromatic compounds more soluble than aliphatic compounds in dimethylimidazolium ionic liquids?
A simulation study Author(s): Hanke C.G., Johansson A., Harper J.B., Lynden-Bell R.M. Chemical Physics Letters, 374, No. 1-2, pp. 85-90 (JUN 4 2003)doi: 10.1016/S0009-2614(03)00703-6 Abstract Molecular dynamics simulations of solutions of benzene in dimethylimidazolium chloride and dimethylimidazolium hexafluorophosphate have been performed with a view to answering the question posed in the title. The difference between the chemical potential of a normal model of benzene and one with no charges was found to depend on the solvent but is at least 4 k(B)T. This difference is sufficient to account for the observed solubility differences. There are substantial changes in the local structure around benzene with and without charges.
