This review gathered and discussed the available results on the thermal hazards, thermal kinetics, decomposition mechanism, autocatalytic behavior, thermal explosion, deflagration ability, and incompatibility hazards associated with the thermal decomposition of methyl ethyl ketone peroxide (MEKPO). The present review constructed a diagram showing all activation energy Ea and log A values for the thermal decomposition of MEKPO. Some disagreement exists in the values of Ea and log A (unit: s−1 M1−n) derived from differential scanning calorimetry; thus, more extensive studies must be conducted to resolve disputes. Nearly no literature exists on the thermal explosion and deflagration ability of MEKPO, and the reactions of MEKPO with incompatible contaminants remain unclear. Concerning the complex decomposition mechanism of MEKPO, experimental determination and identifications of intermediates have not been obtained. Available technology must be improved to enable the collection of accurate data on thermal hazards, thermal kinetics, decomposition mechanisms, explosion and deflagration phenomena, autocatalytic behavior, and incompatibility. This review has integrated an up-to-date summary of the most recent approaches and offers perspectives regarding future research. These current findings can serve as a reference for completing subsequent experimental investigations, theoretical studies, and designs of inherently safer measures for producing or handling MEKPO.

与过氧化甲乙酮热分解综合研究相关的爆炸事件:综述

本综述收集并讨论了与过氧化甲乙酮 (MEKPO) 热分解相关的热危害、热动力学、分解机制、自催化行为、热爆炸、爆燃能力和不相容危害的现有结果。本综述构建了一个图表,显示了MEKPO 热分解的所有活化能E a和 log A值。差示扫描量热法得出的E a和log A(单位:s -1  M 1− n )的值存在一些分歧;因此,必须进行更广泛的研究来解决争议。几乎没有关于MEKPO的热爆炸和爆燃能力的文献,并且MEKPO与不相容污染物的反应仍不清楚。关于MEKPO复杂的分解机理,尚未获得中间体的实验测定和鉴定。必须改进现有技术,以便能够收集有关热危害、热动力学、分解机制、爆炸和爆燃现象、自催化行为和不相容性的准确数据。这篇综述整合了最新方法的最新总结,并提供了有关未来研究的观点。目前的这些发现可以作为完成后续实验研究、理论研究以及设计本质上更安全的生产或处理 MEKPO 措施的参考。
