CH70 and TMCH were extensively employed in relevent chemical industries for the polymerization of styrene and rubber, applied as the agent in the process of polymerization. In addition, we also applied the monoammonium phosphate (MAP) to mixed with the above-mentioned materials to test the extinguishing efficiency. In this study, thermal analysis was used to realize the explosive materials exothermic and endothermic phenomenon and decomposition process by differential scanning calorimetry (DSC). Results by this study indicated that reaction heat of CH70 and TMCH were high than 1,300 J/g and 1,200 J/g, separately. Inhibition reaction was very significantly, while CH70 mixed with MAP. Kinetic and safety parameters can be used in the manufacturing process for preventing the accident.
