2,4,6-三硝基-2,4,6-三氮杂环己酮生成历程的~(15)N示踪原子研究

该文用~(15)N示踪原子对DPT上不同类型的胺基氮原子分别进行标记。有~(15)N标记的DPT在硝解剂中生成的硝解碎片分子与脲或硝基脲进行曼尼希缩合反应生成2,4,6-三硝基-2,4,6-三氮杂环己酮产物,用质谱分析法鉴定反应物和产物中~(15)N原子的分布及丰度。研究结果表明:DPT上两种不同的胺基氮原子所在的硝解碎片分子的反应性是很不相同的。三亚甲基胺基氮原子100％地进入产物分子的4位,而硝基胺基氮原子100％地不进入产物分子。

Study on Mechanism of Producting 2, 4, 6-Trinitro-2, 4, 6-Triazacyclohexanone by ~(15)N Tracer Atoms.

In this paper, the two kinds of different nitrogen atoms ofamino groups in DPT molecule had been labelled with ~(15)N atoms respectively.The nitrolysis fragments produced in DPT nitrolysis process could condensedwith urea or nitrourea to from product 2, 4, 6-trinitro-2, 4, 6-triazacyclohex-anone (Mannich reaction). With the help of MS isotopic analysis, the isotopicdistrubution and abundance of ~(15)N tracer atoms in product and reactantmolecule could be determined. The research results showed: The condensationreactivity of two kinds of nitrogen atoms of amino groups in DPT moleculewas very different. Nitrogen atoms of the trimethylene amine groups appeared100% in the 4 position in product molecule, but nitrogen atoms of the ni-troamino groups disappeared completely in the product molecule.
