摘要
主要介绍了煤的熔剂抽提过程中抽提溶剂的选择 (相似相容 )和煤种、溶剂、煤的岩相组成、抽提条件等影响抽提率的因素 ,以及使用柱色谱、薄层色谱和固相萃取等方法对样品进行前处理 ,并通过质谱、凝胶渗透色谱和液相色谱 -质谱联用仪等现代仪器分析手段测定抽提物的组成、结构等的研究方法 ,揭示了煤中部分有机质的分子结构和分子量分布等性质 。
The progress of the solvent extraction of coal and the characterization methods of extracts were reviewed.We focused on the introduction of solvent selection,the analysis of the factors,kind of coal,solvents,macerals on the extraction yield.And the disposal of the sample using columm chromatography(CC),thin linear chromatography(TLC)and solid phase extraction(SPE),the characterization methods of coal extracts,such as mass spectrometry(MS),gel permeation chromatography(GPC),liquid chromatography mass spectrometry(LC MS)and so on.And many properties of coal extracts were revealed.
