“…Tian et al studied the thermal stability and the thermal decomposition mechanism of 1-((cyano-1-methylethyl) azo) formamide, an initiator that has the inherent property of being decomposed at high temperatures with considerable amounts of heat generated. The thermal hazard of CABN is the main consideration in the occurrence of serious accidents [ 58 ].…”

Advances in on-line thermally induced evolved gas analysis (OLTI-EGA) have been systematically reported by our group to update their applications in several different fields and to provide useful starting references. The importance of an accurate interpretation of the thermally-induced reaction mechanism which involves the formation of gaseous species is necessary to obtain the characterization of the evolved products. In this review, applications of Evolved Gas Analysis (EGA) performed by on-line coupling heating devices to mass spectrometry (EGA-MS), are reported. Reported references clearly demonstrate that the characterization of the nature of volatile products released by a substance subjected to a controlled temperature program allows us to prove a supposed reaction or composition, either under isothermal or under heating conditions. Selected 2019, 2020, and 2021 references are collected and briefly described in this review.

“…Therefore, it is necessary to select appropriate reference materials for standardization, especially when there are many parameters. Our research team not only performed thermal hazard analysis and evaluation of energetic chemicals such as nitro compounds, azo compounds, and organic peroxide compounds in the early stage. − On this basis, combined with the QSPR models of partial parameters and corresponding predictive values, a classification method suitable for aromatic nitro compounds was proposed . However, considering the accuracy and complexity of parameter calculation, there are few studies in the literature on the thermal risk classification of aromatic nitro compounds by using simpler means such as optimal molecular descriptor subsets instead of parameters.…”

The thermal hazard of reactions caused by the inherent properties of aromatic nitro compounds has long been a concern for the chemical industry. At this time, thermal hazard assessment is critical for safe operation and standardized storage involving nitration. In this work, based on the molecular structures of 18 aromatic nitro compounds and the selected six typical calorimetric parameters, a thermal hazard assessment method dominated by the optimal descriptors subset was proposed by quantitative structure−property relationship modeling. Finally, the optimized thermal risk matrix and thermal hazard levels of nitramines were given. By comparing the previous thermal classification standards, it is found that the classification results of the proposed method are consistent with the traditional methods on the whole and can reasonably solve problems, such as the single evaluation parameter, the underestimated thermal hazard level, and the difficulty of distinguishing high-energy nitro compounds one by one.
