2-硝亚胺基-5-硝基-六氢化-1,3,5-三嗪(NNHT)的合成

Synthesis of 2-Nitroimino-5-nitrohexahydro-1,3,5-triazine(NNHT)

以甲醛、特丁胺和硝基胍为原料,经过Mannich缩合反应和氯离子催化硝解反应得到2-硝亚胺基-5-硝基-六氢化-1,3,5-三嗪(NNHT),利用核磁共振光谱、红外光谱和元素分析等鉴定了其结构,研究了温度对Mannich缩合反应的影响,优化了硝解反应条件。结果表明,在80℃时,Mannich缩合反应的收率达89%;当硝解反应温度提高到20℃时,收率可提高到94%,用工业硝酸代替纯硝酸在室温下进行硝解反应,收率可达88%。

Taking formaldehyde, tert-butyl amine and nitroguanidine as primary materials, 2-nitroimino-5- nitrohexahydro-1, 3, 5-triazine （NNHT） was obtained by the process of nitration and Mannich reaction. Its structure was identified by NMR, IR and elemental analysis. The effect of temperature on Mannich reaction was investigated, the yield reached 89% while the temperature was 80 C. The conditions of nitration were further optimized, the yield rose to 94% while the reaction was controlled under the room temperature. Instead of 100% nitric acid, industrial nitric acid was used in the nitration under the room temperature, and the yield was 88%.
