3-硝基-5-胍基-1,2,4-噁二唑(NOG)与叔丁胺,甲醛进行曼尼希反应,其缩合产物在不同的硝化条件下硝化,制备了2-(3-硝基-1,2,4-噁二唑)亚胺基-5-硝基-六氢化-1,3,5-三嗪(NON-HT),2-(3-硝基-1,2,4-噁二唑)亚胺基-5-亚硝基-六氢化-1,3,5-三嗪(NONsHT),并通过IR,ESI-MS,1H NMR,13C NMR,元素分析等手段进行了表征。利用多重升温速率示差扫描量热法(DSC),并结合Kissinger法和Ozawa法及相关方程估算了NONHT、NONsHT的热动力学参数。结果表明,硝基取代化合物(NONHT)的热稳定性要明显高于亚硝基取代化合物(NONsHT),二者的热分解温度也远高于类似物NNHT的分解温度。3-硝基-1,2,4-噁二唑环的引入有助于提高化合物的热稳定性能。 |

2-(3-nitro-1,2,4 -oxadiazole) imino-5-nitro-hexahydro-1,3,5 -triazine (NONHT) and 2-(3-nitro- 1,2,4 -oxadiazole) imino -5-nitroso-hexahydro-1,3,5 -triazine (NONsHT) were prepared by using nitration of the Mannich condensation product of NOG,tert-butylamine and formaldehyde. All of the compounds were characterized with IR,1H NMR,13C NMR,ESI-MS and elemental analysis. The thermal behaviors of NONHT and NONsHT were studied by using multiple heating differential scanning calorimeter (DSC). Their thermal decomposition kinetic parameters and thermodynamic parameters were calculated by using Kissinger,Ozawa and other methods. The results show that the thermal stability of NONHT is better than that of NONsHT. Their much higher decomposition temperatures than NNHT indicate that the introduction of 3-nitro-1,2,4 -oxadiazole ring can improve the thermal stability significantly. |
