Ionic liquids (ILs) were considered to be immobilized on solid supports to overcome the problems of the pure ILs in fuel desulfurization. Take Merrifield resin as solid support, four polymer-supported imidazole ionic liquids (PSILs) with different lengths of alkyl chain linkers were prepared by covalent binding and the structures were characterized by Fourier transform infrared (FTIR), elemental analysis,...
ImCl-silica gel (SG-ImCl) was prepared by directly immobilized [1-methylimidazole][Cl] (ImCl) onto silica gel (SG) using co-condensation of ionic liquid modified organosilane and tetraethoxysilane (TEOS) as silica source in strong acid condition. The properties of the samples were characterized by FTIR, elemental analysis, 29Si MAS NMR, SEM, BET. The results suggested that [1-methylimidazole][Cl]...
