| 摘 要： | 以N-甲基咪唑为原料,经过两步硝化反应得到1-甲基-2,4,5-三硝基咪唑(MTNI),并用红外光谱、核磁共振、元素分析对其结构进行了表征.研究了发烟硝酸与发烟硫酸的体积比、加料顺序、反应时间、温度对1-甲基-2,4-二硝基咪唑(2,4-MDNI)和MTNI收率的影响.结果表明,当一段硝化采用正加法加料,发烟硝酸与发烟硫酸的体积比1:2,二段硝化采用反加法加料,发烟硝酸与发烟硫酸的体积比1:4,反应时间2h,反应温度110～115℃时,产物得率较高.

| Abstract: | 1-Methyl-2,4,5-trinitroimidazoles(MTNI) was synthesized with 1-methylimidazole as initial material by two steps nitrification reaction.Its structure was characterized by IR,1 H NMR and elemental analysis.The effect of the drip order,ratios of volume for nitric and sulfuric acid,reaction time,temperature on the yield of 2,4-dinitroimidasole(2,4-MDNI) and MTNI was investigated.The results show that the conditions of good yields are: the drip order of additive of the first step,ratios of volume for nitric and ... |
