摘要:亲二烯体试剂4 甲基 1,2,4 三唑啉 3,5 二酮(MTAD)与共轭二烯成分形成衍生物,经气相色谱 质谱分析,衍生物质谱图中各种特征碎片离子简单、明显,可用于确定共轭双键在碳链中的位置。以鉴定云南松毛虫性信息素腺体成分的共轭双键位置为例,进一步探讨了反 5 ,顺 7 十二碳二烯醇及相应的醛和乙酸酯与MTAD形成衍生物的化学反应特点及色谱分析中应注意的问题。
The dienophile 4-methyl-1,2,4-triazoline-3,5-dione (MTAD) adducts of conjugated diene compounds were used to locate the position of the conjugated double bonds in the parent compounds by high-resolution gas chromatography and electron impact mass spectrometry. Their mass spectra are marked by recognizable molecular ions and abundant diagnostic ions that allow the determination of the diene position. With the identification of the sex pheromone gland extracts of Yunnan pine caterpillar moth Dendrolimus houi as an example, the characteristics of reaction of (E,Z)-5,7-dodecadien-1-ol (E5,Z7-12:OH) and its corresponding aldehyde and acetate with MTAD are discussed. Potential problems in gas chromatographic analysis are also discussed.
