Application of Quaternary Aminated β-Cyclodextrin Ionic Liquid Stationary Phase in Capillary Gas Chromatography

Abstract

Two kinds of quaternary aminated β-cyclodextrin ionic liquids were synthesized and used as stationary phases in capillary gas chromatography. The influences of different counter ions (tetra- borofluoride, bis-trifluoromethanesulfonylimide) were studied. The results indicated that quaternary aminated β-cyclodextrin ionic liquids possessed good column coating properties and a chromatographic separation abilities. The Grobs mixture, alkanes, alcohols and aromatic position isomers, such as xylene, nitrotoluene, dichlorobenzene and cresol were separated well. These quaternary aminated β-cyclodextrin ionic liquids have potential to separate some complex compounds including alcohol, amine, ester etc.

New ternary water-soluble support from self-assembly of β-cyclodextrin-ionic liquid and an anionic polymer for a dialysis device

“…In the majority of the reported cases, the IL is covalently bound to the CD rim. As an example, ionic liquid grafted by the nitrogen atom of imidazolium on the primary face of β-cyclodextrin was immobilized on modi ed silica and used as chiral support in high-performance liquid chromatography (Rahim et al 2016a;Rahim et al 2016b), in capillary gas chromatography (Zhang et al 2011) or in capillary electrophoresis (Zhou et al 2017) (Fig. 1a).…”
