爆炸现场提取物中过氧化甲乙酮的鉴定方法

Identification of Methylethyl Ketone Peroxide in Extracts from Explosion Scene

本文提出一种利用离子色谱法辅以其他仪器分析方法鉴定爆炸现场残留物中分解产物的方法来鉴定过氧化甲乙酮的方法。由于过氧化甲乙酮性质极不稳定,易分解成二氧化碳、甲酸、乙酸、丙酸、丁酮等产物,本文利用离子色谱法鉴定水溶液中甲酸、乙酸、丙酸,应用气相色谱及气相色谱质谱联用技术鉴定顶空气体中二氧化碳及丁酮,从而实现对爆炸现场提取物中主要成分进行定性分析,方法准确可靠。

An ionic chromatography together with other instrumental analytical method was proposed for the identification of MEKP in residue of explosion scene by identifying its decomposition products.MEKP can easily decompose into formate,acetate,propionate,carbon dioxide and butanone,therefore we use ionic chromatography to identify formate,acetate and propionate in aqueous solution,GC and GC-MS to identify carbon dioxide and butanone over headspace of samples,and thus accurate qualitative analysis of MEKP was obtained based on the test results.
