摘　　要：煤中低分子化合物作为煤有机质的重要组成部分，日益受到人们的广泛关注。在综合评述国内外关于低分子化合物的研究历史、现状及面临的问题的基础上，提出将超声波同传统溶剂抽提相结合用于研究煤中低分子化合物。As the important part of coal organic structures, low molecular weight compounds in coal and its effect on coal conversion features has been increasingly received interests recently. In this paper, the stories of research and the current problems in the fields of low molecular compounds researches were systematically reviewed. Based on the discussions, ultrosound technology combined with traditional solvent extraction of coal as a new method to investigate the properties and distributions of low molecular weight compounds and their relations with skeleton strctures of coal was proposed.
