The thermal decomposition characteristics and the thermal safety parameters of 2,2-di(tert-butylperoxy)butane (DBPB) was investigated by differential scanning calorimetry (DSC). The apparent activation energy (Ea) was evaluated by three different kinetic analysis methods based on the DSC experimental results. By the method of Malek, Zhuravlev-Lesokhin-Tempelman (Z-L-T) equation was the most probable mechanism function of DBPB decomposition. Furthermore, for the safety of storage and transportation, the self-accelerating decomposition temperature (SADT) of 50 kg standard packaged 50% w.t. DBPB solution was calculated by Semenov model. And the decomposition products were separated and identified by gas chromatograph/mass spectrometer (GC/MS). The decomposition process of DBPB was inferred which may help us to interpret the decomposition mechanism of di-functional peroxides. Finally, the findings of this study could do a contribution to preventing the thermal hazardous accidents, which would happen during DBPB chemical process, transportation and storage.
