Synthesis of 2,4,6-Trinitro-3,5-diamino-N-(1,2,4-triazole-4)-aniline

2,4,6-T rinitro-3,5-diamino-N-(1,2,4-triazole-4)-aniline was synthesized using 2,4,6-trinitrochlorobenzene as the start material which firstly reacted with methylamine alcohol solution,then reacted with sulfuric acid and nitric acid,and finally reacted with 4-amino-1,2,4-triazole(AT A) and methanol sodium.The total yield is 80.18%.The target compound and its intermediates were identified by IR,MS and1HNMR.The main affecting factors of the reactions were discussed based on reaction mechanism.The results of the DSC test show that the tw o thermal decomposition peak temperature are respectively 210 ℃ and 328 ℃.The results of the T G test show that there is not any obvious quality loss process below 200 ℃,and the residual decomposition is 38.89% when the temperature is up to 500 ℃,indicating the final compoud has good thermal stability.
