中文摘要：
采用CS2对童亭亮煤进行索氏萃取和超声萃取,用气相色谱/质谱联用仪（GC/MS）对相关萃取物进行分析,结果表明：童亭亮煤的索氏萃取物由正构烷烃和芳烃构成,而超声萃取物还检测到异构烷烃和各类杂原子化合物,并且随着超声萃取时间的增加,所检测到的物质种类更多结构也更复杂;而超声波的空化效应产生的冲击流能促进溶剂和煤样的传质,使超声波在短时间内能将索氏萃取不能萃取出的化合物释放出来。
英文摘要：
Clarain from Tongting bituminous coal was extracted with CS2 using soxhlet extraction and ultrasonic extraction,and then the extracts were analyzed with GC/MS.The results indicated that the soxhlet and ultrasonic extracts from clarain composed with normal alkanes and aromatic,and branched alkanes and heteroatomic compounds were also detected in the ultrasonic extracts.Along with the increase of ultrasonic extraction time,the variety of detected substances was more,and the structure was more complex too.Impact flow generated by ultrasonic cavitation accelerated the mass transfer rate of solvent and the matrix,and as a result,some compounds which could not be extracted by soxhlet extraction were able to be released by ultrasonic extraction in short time.
