摘　　要：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.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.
