Runaway reactions of organic peroxides (OPs) are a significant issue in process safety, due to their fragile bonds and extensive heat release during abnormal conditions. As one of the typical OPs and an intermediate in the process of producing phenol, cumene hydroperoxide (CHP) is likely to mix with its products and lead to an uncontrollable self‐accelerating decomposition reaction. In this study, the thermal hazard of CHP mixed with four products separately was evaluated and identified using accelerating rate calorimeter technology. Experimental data illustrated that the maximum pressure rise rate had greatly increased from 1.1 to 15.5, 18.3, and 41.5 bar min−1, and the maximum self‐heating rate had dreadfully raised from 5.4 to 107.7, 116.9, and 231.0°C min−1, when CHP mixed with its products from methanol to phenol, acetophenone, or dimethylphenyl carbinol, respectively. These phenomena indicated a precarious and dangerous reaction decomposition mechanism of CHP after its products mixed under runaway conditions. This work is expected to help researchers and even industrial workers to better identify the potential thermal hazard of CHP in the presence of products; in particular, experimental and calculated parameters are necessary for the appropriate choice of safe conditions of application, waste disposal, storage, and transportation of CHP.

1-nitroso-2-naphthol has thermal instability of thermal decomposition, spontaneous combustion and even explosion. Its thermal decomposition characteristics were tested by synchronous thermal analyzer (TGA/DSC); The activation energy of the thermal decomposition process was calculated by Kissinger method; The infrared absorption characteristic spectra of the gas products produced in the thermal decomposition process were measured by TGA/DSC-FTIR, and the thermal decomposition reaction process was speculated. The results show that the initial temperature (Tonset) of TGA exothermic decomposition of 1-nitroso-2 naphthol is between 129.01-155.69℃, and the faster the heating rate(β), the higher the Tonset, but the faster the thermal decomposition rate, the greater the heat release and the worse the thermal stability. The activation energy (E) of the thermal decomposition process is 83.323 kJ/mol calculated by Kissinger method. The dynamic test results of TGA/DSC-FTIR show that the main reaction of 1-nitroso-2 naphthol during heating is intermolecular dehydration to form ether, and the secondary reaction is decomposition into aliphatic nitro compounds, carbonyl compounds and amines. Sodium hydroxide will reduce the thermal stability of 1-nitroso-2 naphthol. After adding sodium hydroxide, the thermal decomposition process of 1-nitroso-2 naphthol has changed. The main reaction is that 1-nitroso-2-naphthol reacts with sodium hydroxide to produce sodium nitrophenol, which is further decomposed into aliphatic nitro compounds.

Finding new insensitive high explosives has been the focus of the energetic materials community in recent decades. To accelerate the discovery process, it is necessary to elucidate the relationship between molecular structure and the performance of explosives. In this regard, the effects of N‐oxide groups, commonly introduced to increase the energy density of explosives, on the thermal stability of explosives were investigated by comparing the thermal behaviors of a typical energetic N‐oxide, ANPZO, and its analogue ANPZ. The presence of N‐oxide facilitated the thermal decomposition of ANPZO thoroughly and suppressed its sublimation to a certain extent. Compared to ANPZ, the introduction of N‐oxide increased the thermal enthalpy, reduced the solid residues, and shortened the acceleration period of thermal decomposition of ANPZO. Additionally, the sublimation rate and vapor pressure of ANPZO were lower than those of ANPZ. The enthalpy of sublimation for ANPZO was 175.1 kJ mol−1, compared to 135.2 kJ mol−1 for ANPZ. The effects of N‐oxide on the thermal decomposition and sublimation are attributed to its contribution to the augmentation of oxygen sources and intermolecular interactions, respectively. This study provides further insight into the relationship between the N‐oxide group and the performance of explosives, which could be beneficial for the design and application of new explosives.
