Abstract

Liquid organic peroxides have been broadly employed in the process industries such as tert-butyl peroxy-2-ethyl hexanoate (TBPO). This study investigated the thermokinetic parameters of TBPO, a typical liquid organic peroxide, by isothermal kinetic algorithms and non-isothermal kinetic algorithms with thermal activity monitor III, and differential scanning calorimetry, respectively. An attempt has been made to determine the thermokinetic parameters by simulation software, such as exothermic onset temperature (T 0), maximum temperature (T max), decomposition (ΔH d), activation energy (E a), self-accelerating decomposition temperature, and isothermal time to maximum rate (TMR iso). A liquid thermal explosion model was established for a reactor containing liquid organic peroxide of interest. From experimental results, liquid organic peroxides' optimal conditions for avoiding a violent runaway reaction of storage and transportation were created.
