Isothermal microcalorimetry can be used to investigate the thermokinetic parameters for reactive mechanisms. Benzoyl peroxide (BPO), a typical organic peroxide, undergoes an autocatalytic reaction under isothermal decomposition. It requires intrinsically safer design of preparation, manufacturing, transportation, storage, and even disposal. The scope of this study was to describe the exothermic reaction and reaction model of BPO and mixed with benzoic acid by the thermal activity monitor III (TAM III). The results showed the isothermal kinetic parameters, such as activation energy (E (a)), frequency factor (A), heat of decomposition (Delta H (d)), and time to maximum rate under isothermal conditions (TMR (iso)), which were necessary and useful to insure safe storage or transportation for self-reactive substances applied in the process industries.
