【摘要】 在乙酸乙酯溶剂中,以碘甲烷和对二甲氨基苯乙酮反应合成了碘化三甲基对乙酰苯基铵,通过红外光谱和核磁共振氢谱表征了其分子结构.结果表明,在碘甲烷过量50%条件下,反应时间4h,生成的产物可自行从溶液中沉淀出来,产率达85%以上.更多还原

【Abstract】 p-acdophenyl trimethyl ammonium iodide was synthesized with p-dimethyamino acetophenone and methyl iodide in ethyl acetate solution.The structure was characterized by infrared spectroscopy and nuclear magnetic resonance spectroscopy.The effect of reaction conditions on the yield was investigated.The results showed that in ethyl acetate solution,when the methyl iodide was used by an excess of 50%,the resulting product will precipitate out of the solution.When the reaction time lasts for 4hours,the yield can reach 85%.更多还原
