Reaction thermal runaway is one of the most important reasons leading to chemical accidents. With the rapid development of the chemical industry in the world, especially the fine chemical industry, various safety accidents also occur frequently. Therefore, it is necessary to study the exothermic behavior of the reaction process. In this study, reaction calorimeter was used to study the exothermic phenomena during the chlorination reaction and amination reaction. Differential scanning calorimetry was performed on the reactants, and thermogravimetric experiments were performed on the products. In addition, adiabatic experiment was performed to study the thermal runaway behavior of amination products under adiabatic conditions. The results showed that the target reactions generated a large amount of heat in the initial stage. The maximum temperature of amination reaction is higher than the initial decomposition temperature of the amination product under adiabatic condition. The pyrolysis of amination product was divided into three stages. The product had a high apparent activation energy at the beginning of decomposition, and the apparent activation energy decreased as the decomposition progressed.

反应热失控是导致化学事故的最重要原因之一。随着世界化学工业特别是精细化学工业的迅速发展，各种安全事故也屡屡发生。因此，有必要研究反应过程的放热行为。在这项研究中，反应量热仪用于研究氯化反应和胺化反应过程中的放热现象。对反应物进行差示扫描量热法，并对产物进行热重实验。此外，进行了绝热实验，以研究绝热条件下胺化产物的热失控行为。结果表明，目标反应在初始阶段产生了大量的热量。在绝热条件下，胺化反应的最高温度高于胺化产物的初始分解温度。胺化产物的热解分为三个阶段。产物在分解开始时具有高的表观活化能，并且随着分解的进行，表观活化能降低。
