| Abstract: | Methyl ethyl ketone peroxide (MEKPO) is generally applied to manufacturing in the polymerization processes. Due to thermal
instability and high exothermic behaviors of MEKPO, if any operation is undertaken recklessly or some environmental effect
is produced suddenly during the processes, fires and explosions may inevitably occur. In this study, thermal analysis was
evaluated for MEKPO by differential scanning calorimetry (DSC) test. Vent sizing package 2 (VSP2) was used to analyze the
thermal hazard of MEKPO under various stirring rates in a batch reactor. Thermokinetic and safety parameters, including exothermic
onset temperature (T
0), maximum temperature (T
max), maximum pressure (P
max), self-heating rate (dT dt
−1), pressure rise rate (dP dt
−1), and so on, were discovered to identify the safe handling situation. The stirring rates of reactor were confirmed to affect
runaway and thermal hazard characteristics in the batch reactor. If the stirring rate was out of control, it could soon cause
a thermal hazard in the reactor. |
