| Popis: | 93 Benzoyl peroxide (BPO) has been used as initiator or medicine. In Taiwan and Japen, several severe fire and explosion incidents had occurred due to its thermal reactivity and explosive properties. In this study, the thermal decomposition of BPO was characterized by the isothermal microcalorimeter, TAM (Thermal Activity Monitor). It could investigate the thermal hazards while storing BPO and determine its thermokinetic data on isothermal condition. Thermograms show that in the temperature range from 70℃ to 90℃, follows the autocatalytic reaction. In addition, the reaction order, activation energy and rate constant are verified be 0.9, 163 KJ/mol and 4.38×1018 exp (-163, 230/8.314×T), respectively. Finally, the practical suggestions can be provided to prevent the specific plant from accidents, especially at low temperature conditions during storage and transportation. |
