tio2 nanoparticles were synthesized by modified sol—gel method using pure room temperature ionic liquid(rtil) 2-hydroxyethylammonium formate as a reaction medium. the structure and morphology of tio2nanoparticles were characterized with x-ray powder diffraction (xrd), bet surface analysis and scanningelectron microscopy (sem). tio2 nanoparticles were synthesized in open and closed vessels. the ...
In this research, we have developed cheap recyclable and task-specific acidic ionic liquids (AILs) 1-hydrogen-3-methylimidazolium hydrogen sulfate [Hmim]HSO4, 1-hydrogen-3-methylimidazolium chloride [Hmim]Cl, 2-pyrrolidonium hydrogensulfate [Hnhp]HSO4 and applied them in acid catalyzed synthesis of quinoxaline derivatives from 1,2-phenylendiamines and 1,2-dicarbonyl compounds. The products coul...
Room-temperature ionic liquids are a class of non-molecular ionic solvents with low melting points. Their properties have the potential to be especially useful as stationary phases in gas-liquid chromatography (GLC). A series of common ionic liquids were evaluated as GLC stationary phases. It was found that many of these ionic liquids suffer from low thermal stability and possess unfavorable re...
