Some petroleum refining and petrochemical processing process, such as aromatics extraction, toluene disproportionation of benzene and xylene, toluene and trimethylbenzene alkyl transfer reaction, isomerization of xylene, benzene alkylation with ethylene for preparing ethylbenzene process will encounter C6 C9 aromatics. C6 a C9 aromatic mixture component complex, multi isomer.
By analysis of the Technology Co., Ltd. Tengzhou City Xiangying XiangyingGC7990plus gas chromatograph (GC), using elastic quartz capillary column for separation of C6 ~ C9 aromatic mixture. Time control of pure samples retained by quantitative area normalization method. The accuracy and precision of the method are less than 0.51% and 3.22% respectively.
石油炼制和石油化工的一些加工过程,如芳烃抽提、甲苯歧化制苯与二甲苯、甲苯与三甲苯的烷基转移反应、二甲苯异构化、苯与乙烯烷基化制取乙苯等过程中都会遇到C6一C9芳烃组分。C6一C9芳烃混合物中组分复杂,异构体多。
滕州市翔鹰分析技术有限公司采用XiangyingGC7990plus气相色谱仪，使用弹性石英毛细管色谱柱对Ｃ６～Ｃ９芳烃混合物进行分离。用纯标样保留时间对照进行定性，采用面积归一法定量。该法准确度和精密度分别小于０．５１％和３．２２％。
