摘要：

提出了一种基于聚硅氧烷键合离子液体(PSOIL)的气相色谱固定相的方法, 即首先合成γ-氯丙基聚硅氧烷, 然后通过氯丙基与甲基咪唑的反应合成了聚硅氧烷负载的离子液体, 并对其色谱性能及分离选择性进行了评价.

关键词: 离子液体; 聚硅氧烷; 固定相; 气相色谱

Abstract:

An ionic liquid bonded polysiloxane(PSOIL) was prepared through the reaction between 1-methylimidazole and γ-chloropropyl-polysiloxane and used as gas chromatography stationary phase for the first time. The column efficiency was 3200 plates/m after being conditioned at 210 ℃. Grob reagent, aromatic isomers and homologous series were employed to evaluate the selectivity of the column. The results demonstrate that the PIL stationary phase exerted good selectivity and high separation efficiency.
