“…Particularly, the appearance of DCP as a reaction intermediate has been recently observed by our group during the analysis of the thermal decomposition of cumylhydroperoxide (CHP) in cumene (CUM) [2]. It is, in this context, of great concern to note that thermal decomposition of DCP can likely lead, as a consequence, to temperature control failure and/or process disturbances, to the occurrence of runaway phenomena [3,4]. These may give rise to reactor explosions with significant economic losses and injuries to people.…”

“…A number of severe accidents due to its thermal decomposition have been reported during a recent past and this despite its common use and the efforts devoted to characterize the kinetics involved during its thermal decomposition process. [22][23][24][25][26] A literature survey shows that the thermal decomposition of pure crystalline DCP is a strong exothermal process that develops with large gas and heat evolution following an apparent reaction order kinetic. [22][23][24][25][26][27][28] Table 1 reports the thermokinetic parameters found in the literature cited for the thermal decomposition of DCP.…”

The article investigates the possibility of obtaining reliable information on the adiabatic behavior of thermally unstable substances based on the thermokinetic data collected by differential scanning calorimetric experiments. In particular, it is developed a novel numerical algorithm which allows the estimation of the adiabatic onset temperature. Theoretical results are verified considering the thermal decomposition of dicumyl peroxide carried out under different calorimetric conditions. Encouraging results point out that the procedures developed allow the assessment of adiabatic critical parameters that are very close to the values determined during the experiments.

“…The thermal stability parameters of the two compounds were investigated under nonisothermal conditions. DSC was employed to obtain the thermal decomposition profiles and essential safety parameters such as the exothermic peak temperature ( T p ) and heat of decomposition (△ H d ) . In addition, the thermal decomposition profiles revealed the endothermic peaks of the compounds.…”

To achieve the thermal stability characteristics of azo compounds, a method for characterizing the kinetics of the reaction and decomposition for azo compounds based on nonisothermal calorimetric data was explored. Differential scanning calorimetry (DSC) was employed to analyze the thermal decomposition of two azo compounds, 2,2 0 -azobis(2-methylpropionitrile) and 1,1 0 -azobis(cyclohexanecarbonitrile). DSC experiments were performed to acquire the exothermic peak temperature (T p ), exothermic final temperature (T f ), and heat of decomposition (4H d ). Corresponding thermokinetics were calculated using Flynn-Wall-Ozawa method. Moreover, data determined through DSC experiments were utilized to predict the self-accelerating decomposition temperature, control temperature, and emergency temperature. A nonisothermal experiment was performed to investigate the runaway characteristics of azo compounds, the melting behavior that occurred in the decomposition process interfered with thermal analysis. Through dividing the reaction into several stages, multistage evaluations were carried out in the process of our study. During the thermal explosion simulation, the actual packing parameter of 25.0 kg was applied to ensure that the simulation results were more practical. Thermal safety parameters acquired from the simulation results can provide information on loss prevention and facilitated the establishment of an emergency relief system. Highlights• The decomposition process was divided into several stages and considered melting behavior.• A green method contributes to intrinsic safety design.• Solid thermal explosion was simulated.
