摘要
采用多次萃取的方法从大庆原油中分离出酸性活性组分 ,研究了酸性活性组分与碱水的乳化和界面张力性质 ,并对该组分进行了结构鉴定。
Oxygen containing components are obtained from Daqing crude oil by alkaline/alcohol mixture extraction. The mixed organic acids separated from the acidic components are esterified and identified by gas chromatography/mass spectromety. The results of the structural analysis are given. The emulsification and the dynamic interfacial tension between alkali (N 2CO 3 and NaOH) solutions and the crude oil (original oil, mother oil with acidic components separated out, and simulation oil with acidic components added again) are investigated.
