The results showed that the decomposition of 4-nitroimidazole began with the split of the C—NO2 bond in the temperature range of 185—210℃. The strongly oxidative product NO2 destroyed the instable annulus of 4-nitroimidazole instantly, all the other C=N, C=C, C—H and N—H bonds of the five membered ring were broken simultaneously, and the detected gas products of 4-nitroimidazole decomposition were NO2, CO2 and CO.

结果表明,4-硝基咪唑的催化热分解起始于其分子中C-NO2化学键的断裂,温度范围是185~210℃。C-NO2键的强氧化性的裂解产物NO2瞬间作用于4-硝基咪唑分子中不稳定的五员环,使化学键C=N、C=C、C-H和N-H同时被打破。4-硝基咪唑的气体分解产物包括NO2、CO2和CO。
