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.
