摘　　要：为了解决抽余碳四组分中微量丙二烯和1,2-丁二烯的重复性较差的问题,在保证同等分离效果的前提下,对比分析Al_(2)O_(3)/S毛细管色谱柱和Al_(2)O_(3)/KCl毛细管色谱柱的出峰情况,得出结论:Al_(2)O_(3)/S毛细管色谱柱对微量丙二烯和1,2-丁二烯有较为明显的吸附现象,而Al_(2)O_(3)/KCl毛细管色谱柱对微量丙二烯和1,2-丁二烯没有明显的吸附现象,更适用于含微量丙二烯和1,2丁二烯的碳四组分的检测。In order to solve the problem of poor repeatability of trace MA and 1.2-butadiene in the extracted carbon components,under the premise of ensuring the same separation effect,comparative analysis of chromatogram on the Al_(2)O_(3)/S and Al_(2)O_(3)/KCl chromatographic colum,We can draw a conclusion:there is a relatively obvious adsorption of the trace MA and 1.2-butadiene on Al_(2)O_(3)/S chromatographic column,and Al_(2)O_(3)/KCl chromatographic column didn’t.However,the Al_(2)O_(3)/KCl capillary chromatographic column exhibits no conspicuous adsorption phenomenon for trace amounts of PD and 1,2-butadiene,so,It’s more appropriate for C4 components who contains trace amounts of PD and 1,2-butadiene.
