精蒽生产中蒽的掩蔽现象的气相色谱-质谱研究
Investigation of the Occultation of Anthracene During Refining by Gas Chromatography/Mass Spectrometry
【摘要】 利用气相色谱 /质谱 (GC/MS)技术结合EI源和CI源对石化工业中的蒽残油进行研究 ,发现煤焦油中部分蒽和苯乙烯、苯丙烯、茚等烯烃间发生Diels Alder反应生成六元环化合物 ,揭示了煤焦油中蒽的掩蔽现象的本质 ,进一步扩展了CI源GC/MS在石化工业中的应用。
【Abstract】 Gas Chromatography/Mass Spectrometry (GC/MS) with electron impact ionization and chemical ionization has been used to investigate the occultation of anthracene in coal tar. The occultation of anthracene came from the Diels-Alder reaction with alkene in coal tar, such as phenylethylene, benzylethylene, indene.
