- Decomposition of pentaerythritol tetranitrate (PETN) was monitored at constant volume under variable pressures of NO₂ using differential scanning calorimetry(DSC). Decomposition involved a slow initial reaction followed by an autocatalytic transition at longer times. The apparent induction time(time-to-maximum rate) for autocatalysis was found to be dependent upon sample mass and the initial pressure of NO₂. A global kinetic model consistent with observed product distributions and the free radical chain decomposition mechanisms proposed for simpler alkyl nitrates was found to yield calculated induction times in accord with experiment. 13 refs., 3 figs.
