| 中文摘要 | 合成了不同烷基和卤素取代的咪唑类氯铝酸离子液体([Rm im]X/A lC l3),用电喷雾-离子化质谱和红外光谱表征了离子液体的分子结构、Lew is酸性和极化能力,并将这些性质与离子液体在苯与1-十二烯烷基化反应中的催化性能进行关联。实验结果表明,对于咪唑类氯铝酸离子液体,[Bm im]+A l2C l6B r-具有适宜的Lew is酸性和极化能力,[Bm im]+A l2C l6B r-与1-十二烯的摩尔比为0.005时,1-十二烯的转化率可达93.2%,2-烷基苯的选择性为37.7%。; A series of imidazole-based chloroaluminate ionic liquids with different alkyl and halogen substituents were prepared,and characterized by means of electrospray ionized -mass spectrometry(ESI-MS)and infrared spectroscopy(IR)techniques to investigate molecular structure,Lewis acidity and polarizability of ionic liquids which were correlated with their catalytic performance in benzene alkylation.~+Al_2Cl_6Br~-had proper Lewis acidity strength and polarizability,and best catalytic activity in benzene alkylation among all imidazole-based chloroaluminate ionic liquids.Conversion of 1-dodecene 93.2% with 2-dodecylbenzene selectivity 37.7% was obtained when n([Bmim]~+Al_2Cl_6Br~-) ∶n(1-dodecene)was 0.005.; 国家自然科学基金项目(20436050) |
