对筛选的 6种液态有机化合物 ,考察了其热分解温度、热分解时间和热分解深度之间的关系 .实验表明 ,在 343～ 473K温度范围内 ,过氧化二叔丁基、双环戊二烯和硝酸丙酯对受热温度和受热时间的变化较为敏感 ,热分解现象明显 ,热分解产物易于检测 .尤其是双环戊二烯的分解产物单纯 ,仅有解聚后的环戊二烯一种 ,且价廉、易得 ,值得重视 Six kinds of liquid organic compounds were screened for their thermal decomposition temperature, thermal decomposition time and thermal decomposition depth.The results show that in the temperature range of 343 ~ 473K, di-tert-butyl peroxide, dicyclopentadiene And propyl nitrate on the heating temperature and heating time changes are more sensitive to the phenomenon of thermal decomposition obvious, easy to detect thermal decomposition products, especially the decomposition products of dicyclopentadiene simple, only depolymerization of a cyclopentadiene, And cheap, easy to get, it is worth attention
