| Summary: | 碩士 === 國立雲林科技大學 === 環境與安全工程系碩士班 === 93 === Historically, methyl ethyl ketone peroxide (MEKPO), a universal hardener in the rubber industries, has caused many serious explosions and fires in Taiwan, Japan, Korea, and China. This study used certain thermal analytical methods to thoroughly explore both why MEKPO led to these accidents and what happened during the upset conditions. Potential process contaminants (inorganic acids), such as HNO3、H3PO4、HCl、H2SO4, were deliberately selected to mix with MEKPO for discussing the exothermic phenomenon. Differential scanning calorimetry (DSC) and Vent Sizing Package 2 (VSP2) were employed to evaluate the runaway reaction. The results indicate that MEKPO is highly hazardous when mixed with any of the above-mentioned contaminants. Fire and explosion hazards could be effectively lessened if the safety information are properly imbedded into manufacturing processes.
