摘要
鲁奇媒气化工艺低温轻质媒焦油中酚类化合物经醎提取分离后,在有机溶剂中与乙酐作用形成乙酰桁生物,然后在OV-101石英毛细管柱上得到良好分离.GC-MS鉴定出六十多种1—3个环的酚类化合物,并对其作了定量分析.通过标样的衍生化实验,选取了最佳衍生化条件,方法的回收率达94％以上.
The phenolic fraction of coal tar from Lurgi Coal Gasification process was Isolated by basic extraction and then derivatized by using acetic anhydride in organic solvent. The individual components of the derivatives were separated by gas chromatography with a fused-silica capilicary column coated with OV-101 and were identified by GC-MS. More than sixty 1-3 ring phenolic compounds were identified and determined. Optimum conditions for the deriva-iization were selected and the overall recovery of the method was found to be higher than 94%.
