均苯三乙酮的合成研究

Study on Synthesis of 1,3,5-Triacetylbenzene

摘要: 目的：合成均苯三乙酮。方法：利用甲酸乙酯、丙酮和乙醇钠反应生成不饱和醇钠，然后用弱酸酸化生成均苯三乙酮。结果：成功合成出均苯三乙酮，并通过TLC监测、测定其熔点及质谱和核磁共振氢谱确定其结构。结论：此合成均苯三乙酮的方法操作简单，原料价廉易得，可用于工业上合成较大量的均苯三乙酮。

Abstract: Objective: 1,3,5-Triacetylbenzene was synthesized. Methods: 1,3,5-Triacetylbenzene was prepared by ethyl formate and acetone reaction with sodium ethoxide and then the producing unsaturated sodium ethoxide solution was acidified with weak acid. Results: 1,3,5-Triacetylbenzene was synthesized and confirmed by TLC, melting point, 13C-NMR and 1H-NMR. Conclusion: The operating method of the synthesis of 1,3,5-triacetylbenzene was simple, cheap and easily available for the raw materials, so it could be used for the industrial synthesis of relatively large quantities.
