摘要
用溶剂萃取法从胜利孤东原油中萃取、浓缩出含有机酸的活性组分，用柱色谱分离成窄馏分并进行了波谱鉴定。考察了胜利孤东原油及萃取出酸性活性组分的剩余油与碱水溶液的乳化性质和界面张力性质。结果表明，萃余油失去了原油所具有的与碱水间的良好乳化性质和低界面张力性质。
The oxygen containing components are obtained from Gudong Crude oil of Shengli by solvent extraction and separated into acidic and other components chromatographically on silica gel column. The acidic components are separated into single organic acids and the later are identified by gas chromatography/mass spectrometry. The results of the structural analysis are given. The emulsification and the interfacial tension between alkaline solution and crude oil, both original and after oxygen containing components having been extracted, are investigated.
