应用气相色谱法，采用交联 Ｐ Ｅ Ｇ２０ Ｍ 毛细管柱，程序升温，氢火焰检测器，结合色谱质谱定性，峰面积校正归一法定量，成功地测定了甲苯歧化与烷基转移反应混合芳烃产物中重芳烃组分，测定方法简便，有较高的准确度，可满足生产工艺和科研开发中混合芳烃产物的分析要求。
The effects of toluene disproportionation and transalkylation on mixed aromatics were investigated by gas chromatography with a cross-linked P E G20 M capillary column, programmed temperature and hydrogen flame detector, combined with mass spectrometry and peak area calibration. The heavy aromatic component in the product has the advantages of simple determination method and high accuracy, and can meet the analytical requirements of the mixed aromatic hydrocarbon product in the production technology and scientific research and development.
