| Research Abstract |
The mixing sates of imidazolium-based ionic liquids with benzene and its derivatives, methanol, and water have been observed using small-angle neutron scattering, infrared, NMR, and large-angle X-ray scattering techniques. The cation-π interaction between the imidazolium and benzene rings significantly contributes to the mixing of ionic liquid and benzene solvents. In contrast, the hydrogen bonds among methanol molecules play important role to form methanol clusters in ionic liquid-methanol solutions. In aqueous solutions, ionic liquid with nitrate ion forms spherical micelles.
