摘要

采用毛细管气相色谱法合成了1-烯丙基-3-甲基咪唑离子液体，分别作为柱内和柱外固定相进行了聚合。研究了不同聚合工艺对聚合效果的影响。结果表明，1-烯丙基-3-甲基咪唑六氟磷酸酯离子液体在柱内和柱外聚合后均具有良好的柱包覆性能和色谱分离能力。而外聚合柱比内聚合柱效率高。Grobs混合物、醇类、烷烃和芳香位置异构体，如二甲苯、硝基甲苯、二氯苯和甲酚被很好地分离。这种聚合离子液体具有分离醇、胺、酯等复杂化合物的潜力。

Study on poly methods of imidazolium ionic liquid stationary phase in capillary gas chromatography

1-allyl-3-methylimidazolium ionic liquids were synthesized and polymerized respectively in-column or out-column as stationary phases in capillary gas chromatography. The influences of different polymerized precedure were studied. The results indicated that 1-allyl-3-methylimidazolium hexafluorophosephate ionic liquids possessed good column coating property and a chromatographic separation ability after polymerized either in-column or out-column. While the column by polymerized outside had better column efficiency than that in column. The Grobs mixture, alcohols, alkanes and aromatic position isomers, such as xylene, nitrotoluene, dichlorobenzene and cresol were separated well. This polymerized ionic liquid gave potential to separate some complex compounds including alcohol, amine, ester etc.
