摘　　要：采用原位热解酯化技术对烃源岩非烃组分中含氧化合物的组成进行了探索性研究 ,得到了以一系列一元羧酸甲酯为主的反应产物。这表明 ,采用该方法可以在热解过程中有效地保留脂肪酸中的羧基 ,并能在分子级水平上研究非烃组分中含氧化合物的组成、结构。该方法所需样品量少 ,简单易行 ,热解温度较低 ,对仪器要求不高 ,是研究石油及烃源岩抽出物非烃组分中含氧化合物的有效方法。An in-situ pyrolytic methylation method is proposed and used to analyze the chemical composition of oxygen containing compounds in the resins from source rock solvent extracts. A series of aliphatic monoacid in the pyrolytic methylation products have been detected. The in situ pyrolytic methylation method may effectively prevent the carboxylic functional groups from cracking in the process of pyrolytic methylation reaction and can be used to investigate the chemical composition of oxygen containing compounds in the petroleum and organic matter of source rocks. This method is easy to be operated and has less examples and no special requirement on instrument. The reaction needs a low thermal temperature.
