摘要
以2,4,6-三硝基氯苯、三氯三聚氰与4-氨基-3,5-二硝基吡唑(LLM-116)为原料,设计、合成了1-苦基-4-氨基-3,5-二硝基吡唑(Ⅰ)和2,4,6-三(4-氨基-3,5-二硝基吡唑-1-基)-1,3,5-均三嗪(Ⅱ)两种未见文献报道的LLM-116缩合产物,其熔点分别为:234～236℃、296.5℃(dec.),并采用红外光谱、核磁共振光谱、元素分析等进行了结构表征。探讨了缩合反应机理,合成1-苦基-4-氨基-3,5-二硝基吡唑适宜的反应介质为N-甲基吡咯烷酮,较佳反应温度为70℃,时间16h。
Taking 2,4,6-trinitrochorobenzene,2,4,6-trichoro-1,3,5-triazine and 4-amino-3,5-dinitropyrazole（LLM-116） as primary substances, 1 - （ 2,4,6-trinitrobenzene- 1 -yl ） -4-amino-3,5-dinitro-pyrazole （ Ⅰ ） and 2,4,6-tri （ 4-amino-3,5 -dinitropyrazole- l -yl ） - 1,3,5-triazine（ Ⅱ ） which have not been reported in the literature were synthesized by condensation reaction. Their structures were confirmed by IR, NMR and element analysis, and their melting point are 234 - 236℃ , 296. 5℃ （ dec. ） , respectively. The condensation reaction mechanism was discussed, and the optimal reaction conditions synthesizing 2,4,6-trichoro-1,3,5-triazine are as follows： reaction medium is N-methyl-2-pyrrolidone（NMP） ,temperature is 70℃ and time is 16 h.
