| 摘 要： | 基于多硝基吡啶酮类化合物的较强酸性,设计并在水相中合成了12种新颖的高氮含能盐.利用熔点测定、元素分析、1HNMR、FT-IR、粉末XRD分析技术及单晶X射线衍射分析对其进行了结构表征,证实是目标产物.化合物5的晶体属三斜晶系,空间群P1-;化合物6的晶体属单斜晶系,空间群C2/c.用DSC和TG-DTG技术分析了化合物5和8的热分解行为,研究发现化合物5经历两个峰温为183℃和214℃的吸热过程和一个峰温为278℃的放热过程,而化合物8只有一个峰温为319℃的强放热过程.两个化合物放热过程的焓变分别为-181.37kJ/mol和-382.6kJ/mol.

| Abstract: | Based on the relatively stronger acidity of polynitropyridone(DNP),we designed and synthesized twelve novel high-nitrogen energetic salts in aqueous phase. The products were confirmed by melting point determinations,element analysis,1H NMR,FT-IR,powder XRD analyses and X-ray single-crystal diffraction analyses. The single crystals data of NH4(4DNP) and (C2H5)2NH2(4DNP) indicated that the former belonged to a Triclinic,P1-space group and the latter to a monoclinic,C2/c space group. The thermal decomposition ... |
