通过对东乌煤及其腐殖酸、抽提腐殖酸残煤、抽提沥青质残煤进行傅里叶红外分析,揭示抽提腐殖酸和抽提沥青质实验对煤结构的影响。结果表明:由于酸碱溶液的影响,腐殖酸残煤中芳香烃振动的峰,脂肪烃的伸缩振动峰,3400cm^-1附近的峰都变弱;由于吡啶溶剂的影响,沥青质残煤中反映芳香结构的峰变尖锐;煤样的,随H/C增加有减小趋势,而随着O/C的增加呈增大趋势;煤样中腐殖酸的脂肪链最长,支链最少;腐殖酸残煤的脂肪链最短,支链最多。%The Fourier infrared analysis on extracting humic acid and asphaltene reveal the Dongwu coal, its humic acid, the residual coal after influence of extracting experiment of humic acid and asphaltene on the coal structure. The result shows: under the influe
