| 摘 要： | 以CS2-丙酮混合溶剂作为溶剂,对准东煤进行了常温萃取,并利用气相色谱/质谱联用(GC/MS)技术对萃取物进行分析.结果表明:萃取物中GC/MS可检测成分主要为芳烃、脂肪烃以及含杂原子有机化合物组成.芳烃主要为1-6环的稠环芳烃及其烷基取代衍生物,且以含苯环数为4环的稠环芳烃为主.脂肪烃主要成分为链状烷烃以及少量萜类和甾类衍生物.而含杂原子化合物主要以含氧和含氮元素的化合物为主.

| Abstract: | Zhundong coal was extracted with carbon disulfide-acetone mixed solvent at mild condition and the extract has been analyzed with GC/MS.The results show that the extracts mainly consist of aliphatic hydrocarbons,arenes and heteroatom-containing compounds.Most of arenas are 1-6 ring alkyl substitutes.Aliphatic hydrocarbons primarily consist of n-alkanes,alkenes and small amounts of derivatives of terpanes and sterane.Small amounts of heteroatom-containing compounds are detected,which mainly consist of oxygen-containing compounds and nitrogen-containing organic compounds. |
