These organic peroxides are cumene hydroperoxide (CHP) , di-tert-butyl peroxide (DTBP) , methyl-ethyl-ketone peroxide (MEKP), tert-butyl hydroperoxide (TBHP), benzoyl peroxide (BPO), hydrogen peroxide, lauroyl peroxide (LPO), tert-butyl perbenzoate (TBPBZ), and dicumyl peroxide (DCPO). Test data of organic peroxides were measuremented by DSC (Differential Scanning Calorimeter) and ARC (Accelerating Rate Calorimeter); then we used the TSS (Thermal Safety Software) developed by CISP (ChemInform St. Petersburg) to simulate these organic peroxides. According to the kinetics and TMR (Time to Maximum Rate) from simulation of this work could be assessed these results of risk matrix of runaway reaction, and to identify the degree of hazards. It indicated that the heat of decomposition of organic peroxides with acids or bases are increasing, and the majority degree of risk could cause middle severity and high probability of runaway reaction .
