Evaluation of thermal hazard of azobisisobuty ronitrile using acicular assign rate calorimetry

ABSTRACT

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 temperature, pressure and time has been generated. AIBN decomposes exthothermally and the onset of the decomposition occurs at 56.19°C. The reaction reaches its maximum at 112.28°C. During this temperature range, the self-heat rate, and the time to maximum rate of the reaction were evaluated. The experimental data has been also treated to evaluate the activation energy of the potential runaway reaction
