摘　　要：以PLOT/Al2 O3 石英毛细管柱为分析柱 ,采用氢火焰离子化检测器 ,建立了测定丙烯中烃类杂质含量的毛细管气相色谱法。丙烯中烃类杂质含量测定结果的相对标准偏差小于 5 % ,分析时间约 30min ,测定值与国家标准方法基本一致。该方法操作简便 ,分析速度快 ,准确度高 ,重复性好。Hydrocarbon impurities in propylene were determined with capillary gas chromatography (GC) by using PLOT/ Al 2 0 3 quartz capillary column and flame ionization detector (FID). The relative standard deviations of the results were less than 5%, the analysis process lasted about 30 min. The results were consistent with which given by GB/T 3392-91. The method was easy to operate with high accuracy and good repeatability.
