Dimethyl 2,2′-azobis (2-methylpropionate) (AIBME) is an oil-soluble azo initiator whose nature is unstable. In the chemical process, acids, alkalines or catalysts are often added to catalyze reactions. However, the decomposition process of the azo compounds may change when it is in contact with incompatible substances. In order to investigate the effects of common substances (hydrochloric acid (HCl), sodium hydroxide (NaOH), iron oxide (Fe₂O₃)) on the thermal stability of AIBME, differential scanning calorimetry (DSC) was utilized to obtain thermodynamic parameters. The dynamic calculations were carried out by Kissinger and Ozawa method. Meanwhile, adiabatic calorimeter Phi-TEC II was used to simulate the occurrence of thermal runaway of AIBME mixed with three incompatible substances under adiabatic conditions. Based on the adiabatic kinetic analysis, temperature at the time to maximum rate for 8 h (T_D8) and 24 h (T_D24) were obtained. Self-accelerating decomposition temperature (SADT) was calculated by the Semenov thermal spontaneous combustion theory. Non-isothermal experimental results showed that HCl reduced the activation energy of AIBME and increased its potential risk, while NaOH and Fe₂O₃ had inverse effect. In the adiabatic decomposition process, HCl and NaOH decreased the adiabatic temperature rise $\left(\Delta T_{\text{ad}}\right)$ of AIBME, but Fe₂O₃ had less influence. In addition, calculations for SADT of mixtures indicated that a low temperature environment should be provided for storage and transportation.

2,2'-偶氮二甲基二甲基（2-甲基丙酸酯）（AIBME）是油溶性偶氮引发剂，其性质不稳定。在化学过程中，经常添加酸，碱或催化剂来催化反应。但是，偶氮化合物与不相容的物质接触时，其分解过程可能会发生变化。为了研究常见物质（盐酸（HCl），氢氧化钠（NaOH），氧化铁（Fe ₂ O _3）））关于AIBME的热稳定性，利用差示扫描量热法（DSC）获得热力学参数。通过基辛格和小泽方法进行动力学计算。同时，用绝热量热仪Phi-TEC II模拟了在绝热条件下AIBME与三种不相容物质混合后热失控的发生。基于绝热动力学分析，获得了达到最大速率的时间为8 h（T _D8）和24 h（T _D24）时的温度。自加速分解温度（SADT）是根据Semenov热自燃理论计算得出的。非等温实验结果表明，HCl降低了AIBME的活化能并增加了其潜在风险，而NaOH和Fe ₂ O ₃具有相反的作用。在绝热分解过程中，HCl和NaOH降低了绝热温升$（\Delta {Ť}_{\text{广告}}）$AIBME，但Fe ₂ O _3的影响较小。此外，混合物的SADT计算表明应为储存和运输提供低温环境。
