摘要
采用溶剂萃取、色 -质联用和色 -红联用结合色谱保留值的定性方法 ,分析研究了神府东胜煤 CS2 萃取物的化学成分和结构 ,鉴定出 1 2 0多种化合物 ,并对所鉴定出的单个化合物进行了定量分析 ,讨论了神府东胜煤 CS2 萃取物化学成分的结构特征 .结果表明 :萃取物主要由脂肪烃、芳烃和极性化合物三类成分组成 .芳烃含量在萃取物中占绝对优势 ,且主要为 1 - 4环的烷基取代芳烃 .脂肪烃除主要成分正构烷烃外 ,还有少量的类异戊二烯烃和萜烷 ,极性化合物所占的比例很小 。
The CS 2 extracts of Shenfu coal was analyzed with GC/MS,GC/FTIR and gas charomatography retention value.Over 120 compounds were identified and quantified by capillary GC.The characteristics of the CS 2 soluble fraction were discussed.The results show that the CS 2 extracts mainly consist of aliphatic hydrocarbons,arenes and heteroatom containing compounds.Arenes are dominant components and most of arenas are 1 4 ring alkyl substitutes.Aliphatic hydrocarbons primarily consist of n alkanes with small amounts of acyclic isoprenoids and terpanes.Small amounts of heteroatom containing compounds were detected,which mainly consist of oxygen containing compounds.
