摘要

Cumene hydroperoxide (CHP) is a explosive chemical in the chemical industry in Taiwan that can be identified as organic peroxide (OP). Therefore, CHP can be manufactured using cumene mixed with oxygen or air (21% O2) in the oxidation tower and can be an important chemical and hazardous chemical for dicumyl peroxide (DCPO) process, acrylonitrile-butadiene-styrene (ABS) process, and phenol and acetone manufacturing plant. Since 1981-2010 in Taiwan, plenty of thermal explosion accidents of CHP were recorded and analyzed in Taiwan. Therefore, this study was applied to analyze thermal hazard of CHP using an isothermal calorimeter. The reaction order (n) was calculated to be 0.5 that can be used to simulate a thermal explosion accident and to determine thermokinetics in the CHP oxidation process. This study was applied to analyze thermal hazard of CHP in the oxidation tower using the differential scanning calorimetry (DSC) with isothermal and heating method. The temperature of an exothermic reaction of 30, 80, and 88 mass % CHP can be analyzed less than 90℃ in the oxidation tower. The critical temperature of 30, 80, and 88 mass% CHP can be evaluated less than 100℃.
