| 摘 要： | 用气相色谱/质谱联用技术测定了东胜煤有机溶剂萃取物的化学组成，对其化学成分及化合物分布特征进行了研究。结果表明，萃取物主要由烷烃，芳烃和衍生物三种成分组成，其中烷烃主要是正构烷烃；芳烃是萃取物最主要的成分，以萘系，蒽系，菲系，芴系和芘系的0-3烷基取代物为主，和几种高丰度的5-6环稠环芳烃；衍生物主要是多环芳香族含硫化合物，还有一种煤中首次发现的4-氨基-9-芴酮，含氧化合物仅检测到几种。

| Abstract: | The organic solvents soluble fraction from Dongsheng coal was analyzed with GC/MS, the chemical components and the compounds distribution characteristic in the extract were studied, too. The results show that the step-by-step extracts from Dongsheng coal mainly consist of aliphatic hydrocarbons, aromatic hydrocarbons and derivatives. Aliphatic hydrocarbon primarily consists of direct chain n-alkanes. Aromatic hydrocarbons are dominant components in extract, among which naphthalene, anthracene, phenanthrene, fluorene and pyrene structure containing compounds with 0-3 alkyl substitutes are main components, and several 5-6 rings condensed aromatic hydrocarbons are identified, too. Derivatives mainly consists of sulfur-containing condensed aromatic compounds, and 4-aminofluorenone, a compound which first discovered in coal. Only few oxygen-containing compounds were identified. |
