New insights into kinetics of PETN decomposition from the product and reactant point of view: An investigation with mass spectrometry and differential scanning calorimetry

- PETN decomposition is studied by observing gas evolution and exothermic heat.
- Activation energy obtained for NO2 evolution is consistent with theoretical value.
- Activation energy for PETN decomposition is consistent with that for NO2 evolution.
- Activation energy for PETN decomposition is in the range of 170-176 kJ/mol.
