Aromatics are important basic raw materials for organic chemical industry and occupy an important position in chemical production. Toluene is a member of aromatic hydrocarbons. Coked toluene is one of the important sources of toluene. Its production process contains a small amount of olefins and thiophenes and other compounds for various reasons. These impurities affect the equipment, adsorbents and The catalyst has different degrees of influence, so it is necessary to remove trace impurities in the coking toluene.

Regarding the determination of trace thiophene in toluene, there is currently no ready-made method to find. Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. keeps pace with the times, guided by the scientific development concept, and under the leadership of manager Wang Xiaoying, relying on Xiangying analysis technology The Research Institute, Chromatography Engineering Research Institute, Analysis and Testing Center, and 3 scientific research units have developed the "Special Packed Column for the Determination of Trace Thiophene in Toluene" and successfully determined the content of trace thiophene in toluene. Benzene, thiophene and toluene were effectively separated. satisfaction.



Spectra of packed column for determination of trace thiophene in toluene:

Benzene: 3.9 min; thiophene: 6.1 min; toluene: 7.1 min. The three are separated well. This technology is currently under application for protection.
