Three solid organic peroxides

benzoyl peroxide (BPO)

dicumyl peroxide (DCP) and cyclohexanone peroxide (CCP) were tested by using simultaneous TG-DSC analyzer (SDT Q600) with small sample mass

and the thermal data obtained from different scanning rate were analyzed by the Popescu multiple scanning rate method for the first time.Then

the values of self-accelerating decomposition temperature (SADT) of 25 kg standard package were computed according to the thermal explosion theory.The results showed that the values of activation energy and pre-exponential factor of these three solid organic peroxides by using the Popescu multiple scanning rate method were more precise and more credible than that by using the single scanning rate method.Based on correct calculation of these kinetic parameters

SADT can be accurately safely

easily

quickly evaluated with thermodynamic parameters based on thermal explosion theory.
