摘要
以N-甲基咪唑和1-溴代正辛烷反应合成溴代1-辛基-3-甲基咪唑盐[C_(8)MIm]Br。探讨了[C_(8)MIm]Br在两个方面上的应用。首先,[C_(8)MIm]Br作为中间体经阴离子置换反应制备1-辛基-3-甲基咪唑六氟磷酸盐[[C_(8)MIm]PF_(6)],利用红外和核磁对两种离子液体结构进行表征,确定其分子结构和组成。其次,将[C_(8)MIm]Br和十二烷基苯磺酸钠作为结构导向剂制备具有光催化活性的三氧化钨,三氧化钨对甲基橙溶液的光催化效果可达97%以上。
Synthesis of bromo-1-octyl-3-methylimidazolium salt by N-methylimidazole and 1-bromo-n-octane reaction.The application of[C_(8)MIm]Br in two aspects is discussed.First,1-octyl-3-methylimidazolium hexafluorophosphate[C_(8)MIm]PF_(6) was prepared by[C_(8)MIm]Br though anion substitution reaction.[C_(8)MIm]Br and[C_(8)MIm]PF_(6) had been charactered by IR and H NMR to determine their molecular structure and composition.Second,[C_(8)MIm]Br and sodium dodecylbenzene sulfonate were used as structure directing agents to prepare tungsten trioxide with photocatalytic activity.Photocatalytic of tungsten trioxide effect on methyl orange solution can reach more than 97%.
