“…In the adiabatic experiment, the heat released by the sample decomposition not only induced the temperature rise of the sample, but also induced the temperature rise of the bomb. Therefore, in order to obtain more accurate adiabatic decomposition data, thermal inertia (Φ) was used to correct the measured data. , The corrected equations for Δ T ad and TMR ad are listed as follows: where Δ T ad,s is the adiabatic temperature rise caused by sample decomposition obtained through experiment, K; TMR ad,s is the time to maximum rate under adiabatic conditions which was calculated by measured data, h.…”

In this study, in order to assess thermal runaway risk of two step synthesis reactions, two new risk assessment methods were proposed by combining the new assessment procedure with the risk matrix and the Stoessel criticality diagram. The thermal runaway risks of the tert-butyl peroxybenzoate (TBPB) synthesis process and the tert-butyl peracetate (TBPA) synthesis process, and the influence of the use of the pure target products on the assessment results were also studied by the new methods. The results showed that the new methods could obtain more accurate assessment results of two step synthesis reactions. Some measures should be taken to reduce the thermal runaway risks of the two synthesis processes. Furthermore, the use of the pure target products in the new methods would exaggerate the thermal runaway risks of the two step synthesis reactions.

1,2,5‐Oxadiazole‐Based High‐Energy‐Density Materials: Synthesis and Performance

2019

View full text Add to dashboard Cite

This Review covers the synthesis and performance of the most promising 1,2,5-oxadiazole-based high-energy density materials (HEDMs). These materials comprise a 1,2,5-oxadiazole subunit as a key structural motif linked to various acyclic explosophoric groups or to nitrogen-rich and nitrogen-oxygen azoles: 1,2,4triazole, tetrazole, 1,2,4-and 1,3,4-oxadiazoles. Energetic alliances of two and more 1,2,5-oxadiazole rings linked directly or through heteroatom spacers are also presented. Particular attention is devoted to the installation of different explosophores: nitro, nitramino, azo, azoxy, dinitromethyl, trinitroethyl moieties and their combination. Promising environmentally benign energetic materials with high detonation velocity and pressure, and outstanding insensitivity are summarized. Overall, the presented materials may be considered as next-generation high-performance energetic materials that are superior to commonly used traditional explosives (TNT, PETN, RDX, HMX).

The thermal decomposition of dihydroxylammonium 5,5′‐bistetrazole‐1,1′‐diolate (TKX‐50) with three different particle sizes were studied under adiabatic condition by using accelerating rate calorimeter (ARC). The adiabatic experiment revealed that TKX‐50 had two decomposition stages. Based on the experimental results, the decomposition parameters including the thermal data and pressure data of three kinds of TKX‐50 were used as the hazard assessment indicators. The results revealed that the decomposition of TKX‐50 nanoparticles was the mildest among all of the samples in the first decomposition stage. In addition, the SADT of three kinds of TKX‐50 with different sizes were predicted when stored in the wooden cylinder, and the results showed that TKX‐50 milliparticles exhibited the best thermal stability.
