氮杂环丁烷硝基衍生物的热行为

Thermal Behaviour of Nitrosubstituted Azetidines

用DSC法研究了 15个氮杂环丁烷硝基衍生物在静态空气中的热行为。根据所得结果 ,提出了这些氮杂环丁烷硝基衍生物的相对热稳定性次序 。

The theraml behaviour of fifteen nitrosubstituted azetidines,3,3 dinitroazetidinium dinitramide (1),3,3 dinitroazetidinium nitrate (2),3,3 dinitroazetidinium nitroform salt (3),3,3 dinitroazetidinium 3,5 dinitrobenzoate (4),3,3 dinitroazetidinium picrate (5),3,3 dinitroazetidinium 3 nitro 1,2,4 triazol 5 onate (6),1,3 bis(3′,3′ dinitroazetidine group) 2,2 dinitropropane (7),1 (2′,2′,2′ trinitroethyl) 3,3 dinitroazetidine (8), 3,3 dinitroazetidinium perchlorate (9),1 ( 3′,3′ dinitroazetidineyl) 2,2 dinitropropane(10), 3,3 dinitroazetidinium 2,4,6 trinitrobenzoate (11),bis(3′,3′ dinitroazetidine)ketone (12),1 ( 2′,4′ dinitrophenyl) 3,3 dinitroazetidine (13), 1 (2′,4′,6′ trinitrophenyl) 3,3 dinitroazetidine (14), bis(3′,3′ dinitroazetidineyl)oxalone (15) in static air has been studied by means of differential scanning calorimetry. On the basis of the results obtained,the relative thermal stability order and two relationship between the kinetic parameters,and the exathermic decomposition temperature and thermal explosion critical temperature for above mentioned nitrosubstituted azetidines are proposed.
