【摘要】 以50m×0.25mm交联石英毛细管OV-1柱色质联用分析高温煤焦油的环己烷-乙醚抽提物,鉴定出200余组分,其中稠环芳烃144个,含氮、氧、硫的芳烃分别为39、7和8个。观察到5个未见报道的氮杂芳烃组分,首次同时检测分子量为240（M240）的四个含-CH₂-的异构体,并观察到了分子量高达316～332的芳烃。更多还原

【Abstract】 More than 200 components of high-temperature coal tar were detected,and identified on a HP-5980 GC/MS system with a 50 m×0. 25 mm crossklinked quartz OV-1 column, including 7 single ring aromatics, 144 polynuclear aromatics(PNAs),39 containing nitrogen PNAs, 7 containing oxygen-PNAs and 8 containing su1phur-PNAs. Indylcyanide, 2 isomers of dihydrodibenzoacridine and 2 isomers of aza-methy1cyclopenta[cd]pyrene were identified to be coal tar components. The whole 4 methylenebearing isomers of PNAs with molecular weight of 240 were found to coexist in the coal tar. PNAs with molecular weight up to 316-332 were observed, and tentatively identified.更多还原
