Tyhe influences of acidity and dipentaerythritol hexanitrate (DiPEHN) on the thermal sensitivity of pentaerythritol tetranitrate (PETN) was studied using differential scanning calorimetry (DSC). Decomposition kinetics of PETN with or without DiPEHN, acidic PETN and DiPEHN were also studied by SC to evaluate Arrhenius parameters. The presence of sulphuric acid impurity decreased the thermal stability as well as the activation energy, whereas the nitric acid influence was negligible. Thermal stability of PETN was not affected by the presence of DiPEHN. DiPEHN showed better thermal stability and higher decomposition energy compared to PETN.
