N,N,N’-Tris(benzoyl) trimesinic acid dihydrazide was synthesized from benzoyl hydrazine and trischloride and the structures of N,N,N’-tris(benzoyl) trimesinic acid dihydrazide had been characterized by Fourier transform infrared spectroscopy, 1H nuclear magnetic resonance techniques. The reaction condition was investigated by orthogonal experiment and the optimized reaction condition by orthogonal experiment is molar ratio of benzoyl hydrazine: trischloride 5:1, reaction time 4 h, reaction temperature 70 ºC, the yield is 65.7 %. SEM showed the particles of N,N,N’-tris(benzoyl)trimesinic acid dihydrazide were not completely regular and the average size of the particles was 3-4 μm. At the same time, the optimized geometric structure of N,N,N’-tris(benzoyl)trimesinic acid dihydrazide was carried out by theoretical calculations using the semiempirical method PM3.
以苯甲酰肼和三氯化物为原料合成了N,N,N'-三(苯甲酰基)均苯三甲酸二酰肼,并通过傅里叶变换红外光谱、1H核磁共振等手段对N,N,N'-三(苯甲酰基)均苯三甲酸二酰肼进行了结构表征。磁共振技术。通过正交实验考察反应条件,正交实验优化的反应条件为苯甲酰肼:三氯化物摩尔比5:1,反应时间4 h,反应温度70 ℃,收率65.7 %。 SEM显示N,N,N'-三(苯甲酰基)均苯三甲酸二酰肼颗粒不完全规则,颗粒平均尺寸为3-4μm。同时,采用半经验方法PM3.5进行理论计算,对N,N,N’-三(苯甲酰基)均苯三甲酸二酰肼的几何结构进行了优化。
