摘要
以1-甲基吡唑为原料、硝酸与发烟硫酸为硝化剂,一步硝化得到了不敏感单质炸药1-甲基-3,4,5-三硝基吡唑(MTNP),采用熔点、红外光谱、核磁共振、元素分析及质谱对其进行了结构表征,优化了反应条件。结果表明,反应温度90℃、反应时间6h、摩尔比n(硝酸)∶n(发烟硫酸)=1∶8为最优反应条件,此时目标物MTNP收率为15.2%。采用差示扫描量热法(DSC)分析了热性能,分解温度为272.0℃,其热稳定性良好。
1-Methyl-3,4,5-trinitropyrazole（MTNP）as an insensitive energetic compound was one-step synthesized with 1-methylpyrazole via direct nitration using mixture of nitric acid and fuming sulfuric acid for the first time.The structure of MTNP was characterized by IR,NMR,elemental analysis,and mass spectrum.The reaction conditions were optimized as following：reaction temperature 90 ℃,reaction time 6h,molar ratio of HNO3 and fuming sulfuric acid 1∶8.At this condition,the yield of MTNP can reach up to 15.2%.Thermal behavior of MTNP was studied by DSC.Results show that its decomposition temperature is 272.0 ℃,indicating agood heat stability.
