    摘要: 本研究合成聚離子液體作為耐高溫氣相管柱靜相材料,並進行相關測試。聚離子液體的合成,首先利用咪唑(imidazole)與1-溴-6-氯己烷(1-bromo-6-chlorohexane)進行烷化反應,其次在乙二醇中進行自聚合反應後加入1-乙烯咪唑(1-vinylimidazole)進行高分子末端基修飾,最後以雙三氟甲烷磺醯亞胺化鋰(lithium bis (trifluoromethanesulfon)imide)進行陰離子交換並以偶氮二異丁?(azobisisobutyronitrile)進行自由基聚合反應。單體及高分子之結構以核磁共振光譜做初步判斷,並運用熱重分析測試、相轉移溫度測試及膠體滲透層析法測定聚離子液體的物化性質及其分子量大小,再利用氣相層析儀連接火焰離子偵測器進行醇類、多環芳香烴類、烷類、苯類及脂肪酸甲酯測定。研究結果顯示,熱重分析受溫至414℃時,重量百分比才有明顯下降,膠體滲透層析測得分子量約於110000g/mol,咪唑聚離子液體作為氣相層析管柱靜相對於醇類、多環芳香烴類、烷類、苯類及脂肪酸甲酯也有良好的分離效果及再現性。
    This study is investigation the application of polymeric liquids as high temperture stationary phase for gas chromatograhy. The polymeric ionic liquids systhesis steps was following, the imidazole reacted with 1-bromo-6-chlorohexane to form the monomer first. The monomers were placed in ethylene glycol for self-polymerization, then 1-vinylimidazole was added for terminal group modification. Lithium bis (trifluoromethanesulfon) imide was added for anion exchange. Finally, azobisisobutyronitrile was added for free radical cross linking. The structures of monomer and polymer was determination by nuclear magnetic resonance. The phane change was observed by differential scanning calorimetry. The molecular weight of polymer was determination by gel permeation chromatography. For the column test, a gas chromatography with flame ionization detector was used for compounds separation evaluation. Several types compounds were used for test, including alkanes (C8~C40), alcohols, PAHs, benzenes and the methyl ester of fatty acid.The thermogravimetric analysis results showed that the polymer was decomposed at 414℃. The molecular weight is around 110000g/mole. This columns showed good separation effect for all the test compounds.
