Synthesis and Geometric Structure of N,N,N'-tris(Benzoyl)trimesinic Acid Dihydrazide

Abstract

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.
