Utilizing thermokinetic and calorimetric methods to assess the impact of an initiator on the thermal hazard of diallyl phthalate

Diallyl phthalate (DAP), a crucial raw material in producing resin materials, has been studied widely in terms of its polymerization process and application in material modification. However, less attention has been paid to its safety. In this study, the influence of initiators on the thermal hazard of DAP was examined from various viewpoints by conducting thermogravimetric and differential scanning calorimetry experiments and by performing thermokinetic analysis with multiple models. Moreover, the reaction mechanism of DAP was studied. The three-step autocatalysis reaction simulations agreed well with the experimental findings obtained for DAP. The simulated conversion limit time and time to the maximum rate under adiabatic conditions indicate that the thermal hazard of DAP can serve as a reference for controlling its production and storage temperatures.
