✦ Synopsis

The thermal decomposition of azobisisobutyronitrile (AIBN) has been studied under fully adiabatic conditions in a sealed bomb using an accelerating rate calorimetry technique (ARC). Data relating to temperature, pressure and time have been discussed. AIBN decomposes exothermally and the onset of decomposition occurs at 56.19"C. The reaction reaches its maximum at 112.WC. During this temperature range, the self-heat rate, and the time to maximum rate of the reaction were evaluated. The experimental data have been also treated to evaluate the activation energy of the potential runaway reaction.
