| 摘 要： | 采用溶剂萃取和色 -质联用结合色谱保留值的定性方法 ,分析研究了平朔煤 CS2 萃取物的化学组成 ,鉴定出 1 80多种化合物 ,并对鉴定出的单个化合物进行了定量分析 ;讨论了平朔煤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 2 - 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 ,并首次在煤中发现邻二氯苯 .

| Abstract: | The CS 2 extraction of Pingshuo coal was analyzed with GC/MS and gas charomatography retention value. Over 180 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 extraction mainly consists of aliphatic hydrocarbons, arenes and heteroatom-containing compounds. Arenes are dominant components and most of arenas are 2-4 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 and 1,2-dichlorobenzene was discovered in coal for the first time. |
