【摘要】 以咪唑为起始原料,通过N-烷基化和季铵化反应合成了3种卤代1-苄基-3-甲基咪唑盐类离子液体:氯代1-苄基-3-甲基咪唑、溴代1-苄基-3-甲基咪唑、碘代1-苄基-3-甲基咪唑,以红外、核磁及热失重分析表征了它们的结构,并将它们应用于乙酸正丁酯的催化合成,取得满意的效果.更多还原

【Abstract】 Three ionic liquids,1-benzyl-3-methyl imidazolium chloride,1-benzyl-3-methyl imidazolium bromide,1-benzyl-3-methyl imidazolium iodide were synthesized through alkylation and quaterisation from the material imidazole.These ionic liquids and intermediates were characterized by 1H-NMR,IR and TGA.As catalysts,the three ionic liquids were used in the synthesis of butyl acetate,and satisfactory results were gotten.更多还原
