A range of diazonium salts and their corresponding triazenes have been prepared in order to directly compare their relative thermal stabilities (via initial decomposition temperature) from differential scanning calorimetry (DSC) data. A structure–stability relationship has been explored to investigate trends in stability, depending on the aromatic substituent and the structure of the secondary amine component of the diazonium salts and triazenes. All of the triazenes investigated show significantly greater stability (many are stable above 200 °C) compared with the corresponding diazonium salts, which show varying stabilities.

重氮盐及其对应的三氮烯的热稳定性比较

为了直接比较差示扫描量热法（DSC）数据的相对热稳定性（通过初始分解温度），已经制备了一系列重氮盐及其相应的三氮烯。已探究了结构与稳定性之间的关系，以研究稳定性的趋势，具体取决于芳族取代基以及重氮盐和三氮烯的仲胺成分的结构。与相应的重氮盐相比，所研究的所有三氮烯均显示出显着更高的稳定性（许多在200°C以上稳定）。
