历史上，过氧化氢（H2O2）由于在化学工业中的广泛应用，在世界范围内引起了许多严重的火灾和爆炸。与其它化学材料发生不相容反应也可能产生热危害，在最后阶段可能诱发失控反应。本研究运用热分析的方法，探讨了不相容导致的h2o2热事故，并讨论了这种情况下可能形成的热事故。在本研究中，对不同溶剂，丙烷（CH3COCH3）， Fe2O3, FeSO4, H2SO4, HCl, HNO3, H3PO4, NaOH， LiOH和KOH进行了热危害分析，故意选择不同溶剂分别与h2o2混合，以调查危害程度。采用差示扫描量热法（DSC）评价了混合h2o2的热危害。结果表明，h2o2在与10种物质单独混合时具有很高的危险性，是一种潜在的污染物。如果将安全相关数据适当地嵌入到制造过程中，就可以成功地减少火灾和爆炸危险。
Hydrogen peroxide (H2O2), historically, due to its broad applications in the chemical industries, has caused many serious fires and explosions worldwide. Its thermal hazards may also be incurred by an incompatible reaction with other chemical materials, and a runaway reaction may be induced in the last stage. This study applied thermal analytical methods to explore the H2O2leading to thermal accidents by incompatibility and to discuss what might be formed by the upset situations. In this study, the thermal hazard analyses were conducted with various solvents, propanone (CH3COCH3), Fe2O3, FeSO4, H2SO4, HCl, HNO3, H3PO4, NaOH, LiOH, and KOH which were deliberately selected to individually mix with H2O2for investigating the degree of hazard. Differential scanning calorimetry (DSC) was employed to evaluate the thermal hazard of H2O2-mixed ten chemicals. The results indicated that H2O2is highly hazardous while separately mixed with ten materials, as a potential contaminant. Fire and explosion hazards could be successfully reduced if the safety-related data are suitably imbedded into manufacturing processes.
