摘　　要：从分子设计的角度,用典型的傅-克烷基化反应[1],将甲苯、无水AlCl_3粉末和用4A分子筛干燥过的CCl_4等通过一系列的反应合成了4,4'-二甲基二苯甲酮,确定了化合物的目标产品.通过傅-克烷基化等一系列的实验研究,探讨并研究了实验过程中某些化合物的实验条件,比如催化剂及其用量,反应温度等,通过探究总结出了最佳的合成反应温度,时间以及所使用的溶剂.通过探究合成方法在有机合成反应中的所起到的作用,充分利用其优势路线,并且在前人研究的基础上,在合成方法以及合成条件上进行改进,并简化了实验过程当中的复杂合成路线,由此解决了在以往实验过程中所遇到的合成方面的问题,并提高了产率.In this paper,4,4'-dimethylbenzophenone was synthesized by the typical Friedel-Crafts alkylation reaction in toluene and anhydrous aluminium chloride powder and carbon tetrachloride which was dried with4A molecular sieves.The title product was determined through a series of characterization.We explored and studied the experimental conditions through a number of experiment research,for example,weight of the catalyst,reaction temperature and so on.And we obtained the best experimental process and condition.Some of the traditional test method and experimental process were improved and predigested.Therefore,some relevant problems were solved and the production was increased.
