| 摘 要： | 以甲基肼为原料,与盐酸反应得到盐酸甲基肼,再与二氰二胺在50℃进行缩合环化反应,调节溶液pH值,经重氮化反应合成含能化合物1-甲基-3-氨基-5-硝基-1,2,4-三唑(DNMT),总收率62.3%,纯度99.4%,并用红外光谱、核磁共振、质谱、元素分析等方法表征了其结构。探讨了缩合环化反应工艺条件,确定适宜的反应条件为:溶剂为乙醇,n(C2H3N4)∶n(NH2NHCH3.2HCl)=1∶1.1,pH=8~9,成盐组分是盐酸,重结晶溶剂为丙酮。

| Abstract: | A new energetic compound,1-methyl-3-amino-5-nitro-1,2,4-triazole (DNMT),was synthesized using a new synthetic process from hydrazine dihydrochloride and methyl hydrazine as starting material via condensation,cyclization and diazo-reaction. The yield of DNMT was 62.3% and its purity was more than 99.4%. The structure of DNMT was characterized by IR,MS,NMR and elemental analysis. The condensation synthetical process were discussed in detail. The optimum reaction condition was as follow: alcohol as reaction solvent, n(C2H3N4):n(NH2NHCH3·2HCl)=1:1.1,pH=8-9,hydrochloric acid as acidifying agent,acetone as recryctallization solvent. |
