We read the paper by Guo et al. [1] with interest. The authors have investigated the thermal decomposition kinetics and thermal hazards of 2,2′-azobis(isobutyronitrile), AIBN, by differential scanning calorimetry (DSC) and used the Advanced Kinetics and Technology Solutions (AKTS) software to predict the thermal stability of AIBN in ton and kg scale. The main conclusion of interest is that the self-accelerating decomposition temperature (SADT) of a 50-kg standard package is 63 °C.
