| Abstract: | 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. |
