| 摘 要： | 采用气相色谱／质谱联用技术测定了义马煤CS2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：萃取物主要由脂肪烃、芳烃和杂原子化合物三类成分组成。其中脂肪烃以正构烷烃为主，另有部分三环萜和五环萜类化合物；芳烃的主要组分是芳构化萜烷，其含量在萃取物中最高，还检出少量常规多环芳烃：杂原子化合物主要是含氧衍生物，且多为酮和醇类化合物，含硫及含氮化合物各检测到两种。

| Abstract: | The CS2 soluble fraction of Yima coal was analyzed with GC/MS,the chemical components and the compounds distribution characteristic in the extracts were studied,too.The results show that the CS2 extracts of Yima coal mainly consist of aliphatic hydrocarbons,aromatic hydrocarbons and heteroatom-containing compounds.Aliphatic hydrocarbons primarily consist of n-alkanes with partial tricyclic and pentacyclic terpenoids.Aromatic terpenoids are dominant components in aromatic hydrocarbons and have the most content in the extracts and some conventional polynuclear aromatic hydrocarbons were also detected.Heteroatom-containing compounds mainly consist of oxygen-containing compounds,of which the majority are ketones and alcohols.Two kinds of sulphur-containing compounds and nitrogen-containing compounds were identified. |
