Novel Geminal Dicationic Ionic Liquid as Stationary Phase for Capillary Gas Chromatography

Abstract

One geminal dicationic ionic liquid (IL) was synthesized and coated in column as stationary phase for capillary gas chromatography (CGC). In this study, two times imidazolium cations were reacted with 1,4-bis(chloromethyl)-benzene and then the anions exchanged to bis(trifluoromethylsulfonyl)-imide (NTf2-). The new ILs was coated statically in capillary column. The outcome of the stationary phase was evaluated by separating Grobs mixture, n-alkanes mixture, alcohols mixture and aromatic position isomers mixture such as xylene, nitrotoluene, dichlorobenzene and cresol. The results indicated that new IL possessed good column coating properties and chromatographic separation abilities.

PEG‐DIL‐based MnCl42−: A novel phase transfer catalyst for nucleophilic substitution reactions of benzyl halides

“…Recently, DILs have attracted more attention due to their unique and interesting advantages over traditional ionic liquids, with their attractive properties, such as higher chemical and thermal stability, superior heat capacity, excellent structural tunability, etc. Due to the tunability of DILs, they are suitable for use in many engineering and scientific applications such as separation processes, organic synthesis at high temperature, dye‐sensitized solar cells, stationary chromatography phases and novel high‐temperature lubricants …”
