What is Thermal Study on Picryl Azide (2‐azido‐1,3,5‐trinitrobenzene) decomposition using simultaneous thermogravimetry and differential scanning calorimetry about?

## Abstract Thermal decomposition of picryl azide has been studied under non‐isothermal and isothermal conditions using a simultaneous TG‐DSC technique. Picryl azide melts and then decomposes to give 4,6‐dinitrobenzofurazan oxide which melts again and decomposes to gaseous products. Enthalpies (ΔH) of fusion and decomposition have been calculated. The order of reaction (n) is calculated and found to be one. Arrhenius parameters like specific rate constant (k), activation energy (E~act~) and frequency factor (Z) have been calculated under both conditions using different methods. The values calculated from non‐isothermal and isothermal techniques agree fairly well with each other. The observed lower activation energy when compared with phenylazide and 2‐nitrophenyl azide is probably due to an enhanced ortho effect.
