碳八芳烃异构化反应产物气相色谱分析法的研究

Analysis of C8 Aromatics of Isomerization Reaction by Gas Chromatograph

建立了碳八芳烃异构化反应产物的气相色谱分析方法。该方法是在固定相为PC-WAX毛细管色谱柱上,采用程序升温的方法,用氢火焰检测器在程序升温下,分离非芳产物、乙苯、对二甲苯、间二甲苯、邻二甲苯以及碳十以上产物,该方法分离效果好,准确度高。

An analytical method was established for the isomerization reaction products of C8 aromatics by the gas chromatograph.The method used the programmed temperature and the fixed phase of capillary column was PC-WAX.On the hydrogen flame detection,the products of non-aromatics,ethyl benzene,p-xylene,m-xylene,o-xylene and C10＋ aromatics were separated,and the result showed that the method had good separation efficiency and high accuracy.
