摘　　要：以均苯三甲酸为原料,经过两步法合成了N,N′,N″-三环己基-1,3,5-苯酰胺,并采用红外光谱法及元素分析法对其结构进行了表征。研究了各影响因素对其产率的影响,结论表明:引发剂、反应物质量比为w(N,N-二甲基甲酰胺)∶w(均苯三甲酸)∶w(三光气)∶w(环己胺)=7∶15.8∶62.4∶121,酰氯化反应时间为7.25 h,酰胺化反应滴加温度为30℃,酰胺化反应时间为7 h,收率为94.8%,熔点为359.1~368.7℃。Absract： We used the 1,3,5-benzenetricarboxylic acid as a raw material and applied the two-step modification to synthesize the N,N′,N″-tricyclohexyl-1, 3, 5-benzamides, the structure of which was then characterized by the IR and EA methods. And we investigated the effects of many factors on the yield. The results showed that the molecular weight ratio of w（N,N-Dimethylformamide）∶w（1,3,5-benzenetricarboxylic acid）∶w（Bis（trichloromethyl）Carbonate）∶w（Cyclohexylamine） was 7∶15.8∶62.4∶121, the chlorination time was 7.25 hours,the dropping temperature of amidation was 30℃, the amidation time was 7 hours. The yield rate of N,N′,N″-tricyclohexyl-1, 3, 5-benzamides was 94.8%, and the melting points were 359.1-368.7 ℃.
