The application of polymerization initiators in a process can improve reaction efficiency and reduce energy loss. Azo compounds (azos) provide the required energy and promote polymerization for construction due to the heat release in the decomposition reaction. However, the heat release also brings related thermal hazards due to the lack of proper control. To reduce and avoid possible future hazards, the new azo initiators, 2,2′-Azobis(2-methylpropionamide)dihydrochloride (AIBA) is selected to explore the related thermal properties that are less studied by past literature. For the chemical process, its chemical reaction mechanism is extremely essential. In addition to being an influential foundation for process control, it is also used as a calculation basis for subsequent thermal hazard parameters, which is suitable for evaluating the degree of thermal hazard and emergency response. The assessment program includes kinetic model simulations and consecutive calculation on thermal safety parameters, such as TMRad and TCL for process operations. This study combines the thermogravimetric data with the nonlinear kinetics fitting on thermogram. The fitting results are derived back to the analysis formula which corresponds to the reaction mode to obtain the elementary reaction parameters and establish the kinetics process. The runaway mode and consequent thermal hazard parameters can also be obtained.
