| Abstract: | In
this study, a mixture of methyl ethyl ketone peroxide (MEKPO) with various
contaminants, such as H2SO4
and NaOH, was prepared in order to elucidate the cause of these accidents
and the results of upset conditions. Thermokinetic parameters were acquired
by both differential scanning calorimetry (DSC) and vent sizing package 2
(VSP2). In addition, we simulated the thermokinetic parameters and created
kinetic models for the specific contaminants. The results indicate that the
thermal hazard of MEKPO is less than that of the mixed MEKPO with the above-mentioned
contaminants. Consequently, the evaluated parameters could be used to prevent
any unexpected exothermic runaway reaction or to alleviate hazards to an acceptable
extent, if such a reaction occurs. |
