摘　　要：以偕二硝基丙二醇、甲醛和叔丁胺为原料,经过Mannich反应缩合得到1,3-二叔丁基-5,5-二硝基六氢嘧啶中间体。中间体经硝化反应合成出目标物1,3,5,5-四硝基六氢嘧啶(DNNC),总收率达到76%,纯度达到99%。采用红外、核磁、质谱和元素等分析手段对其结构进行了表征,借助差热扫描分析方法(DSC)研究了DNNC的热性能,并测定了其机械感度。结果表明,DNNC的分解温度为222.2℃,摩擦感度为60%,撞击感度为28.5 cm。表明DNNC具有较好的热稳定性和较低的机械感度。The intermediate 1,3-ditertiobutyl-5,5-dinitrohexahydropyrimidine was prepared via Mannich reaction using 2,2-dinitropropane-1,3-diol,formaldehyde and tert-butylamine as materials, and 1,3,5,5-tetranitrohexahydropyrimidine（DNNC） was obtained finally in total yield of 76% and purity of 99%. The DNNC was characterized by IR,NMR,MS spectra,elemental analyses and DSC. The results show that the decomposition temperature of DNNC is 222.2 ℃,and the friction and impact sensitivities of DNNC are 60% and 28.5 cm, respectively, showing a better thermal stability and lower mechanical sensitivity.
