- Abstract
Hazardous chemicals often have the characteristics of high-energy and high-risk, and environmental factors have a significant impact on them. Trinitrophloroglucinol, as an essential energetic intermediate, is widely used in the modern military, aerospace, and energy fields. It is the representative substance of aromatic nitro compounds. Due to the unique properties of nitro, it has both an electron absorption conjugation effect and an electron absorption induction effect. These two effects lead to nitro becoming an electron absorption group, giving it high energy. For such dangerous substances containing nitro, it is of far-reaching significance to study the impact of environmental changes on their safety status. To determine the thermal safety performance of these substances in different external environments, different calorimetric devices, including thermogravimetry, differential scanning calorimetry, and accelerating rate calorimeter, are used to simulate different storage environments. Combined with calorimetric data, thermokinetic models suitable for trinitrophloroglucinol were established for thermal safety analysis. The results provide some quantitative guidance for the use and storage of aromatic nitro compounds.
