摘　　要：对云南寻甸褐煤氧化降解产物黄腐植酸分子量小于500的组分进行了GC-MS、红外分析及官能团含量的定性定量分析。结果显示,黄腐植酸中小分子组分含有大量的羧基,酚羟基含量较少。GC-MS研究表明,二元羧酸构成了含量上优势化合物,乙二酸、丙二酸、丁二酸为含量较高的化合物;羟基羧酸类以α-羟基丙酸含量最高;醇类、芳香类羧酸、酸性萜类、氨基酸类化合物含量少;内酯类、稠环芳烃环状化合物含量很低或不存在。The low molecular weight fraction of fulvic acid that were extracted from chemolysis brown coal of Xundian form Yunnan were analyzed by gas chromatography-mass spectrometryD（GC-MS）,Fourier transform infrared spectrometry,qualitative and quantitative analysis of chemical function group content.Results indicated that the carboxyl groups were riched in fulvic acid with low contents of phenolic hydroxyl.The GC-MS results showed that the dicarboxylic acid was predominant of the compounds of the fulvic acid,oxalic acid,malonic acid and succinic acid were the characteristic compounds with higher contents,α-hydroxy carboxylic acid was highest amount in the hydroxyl carboxylic acid compounds,and the contents of alcohols,aromatic acid,terpene and amino acids were lower,but lactones and condensed aromatics compounds had a much low amount or inexistence.
