摘要
采用FFAP毛细管柱程序升温,对环己酮、过氧酸氧化法合成的ε-己内酯中间产物进行气相色谱分析。结果表明:试样中各组分的分离效果较好,能准确快速地测出ε-己内酯的含量,ε-己内酯的回收率为99%～101%,相对标准偏差为0.36%。
The intermediate in ε- caprolactone synthesis from cyclohexanone by peracid oxidation was analyzed with capillary columns by temperature-programmed gas chromatography. The results showed that the components of the samples can be separated well and the content of ε- caprolactone can be measured rapidly and accurately. The recovery rate of ε- caprolactone was 99% - 101% and the relative standard deviation was 0.36%.
