摘　　要：为了揭示煤中可溶组分的赋存形式和溶出行为,用溶剂CS2对梁家长焰煤镜质组(LJJY)进行了索氏萃取,对按时间段分批(次)提取萃取物进行了FTIR和GC/MS的定性分析和定量分析.结果表明,LJJY用CS2溶剂进行索氏萃取时,初期萃取速率较快,后期减慢,总萃取率不高;CS2可溶物的溶出过程为:萃取初期溶出的主要是脂肪烃而取代芳烃较少,随反应进行,脂肪烃溶出量越来越少而取代芳烃含量则相对增多,此后溶解的主要是非取代的芳族化合物和含氧化合物;煤变质过程中主要存在着三类反应即芳构化反应、裂解碎化稳定反应和缩合反应.To reveal the exiting state and solubilization behavior of solule components in coal, vitrinite from Liangjia long flame coal （LJJY） was extracted using Soxhlet extractor with CS2 and soluble components sampled as time in batches or times were analyzed using FTIR and GC/MS for qualitative and quantitative analysis. The results show that the initial extraction rate of LJJY extracted using Soxhlet extractor with CS2 is rapidder, subsequently slows down and the total extraction rate is not high. The dissolution process of CS2 extracts as follows： more alipha- tic hydrocarbons and less substituted aromatics are dissolved in early extraction, over time, ali- phatic hydrocarbons decrease and substituted aromatic contents relatively increase, and finally the non-substituted aromatic compounds and oxygen-containing compounds are main dissolution. The process of coal metamorphism mainly exists three types of reaction, which are aromatization reac- tion, splitting and stability reaction and condensation reaction.
