摘　　要：本研究以重烷基苯和十二烷基苯为原料合成磺酸盐型阴离子Gemini表面活性剂,并用其盐水溶液对原油进行界面张力测试,研究了不同条件下合成出的Gemini表面活性剂及其浓度对原油界面张力的影响。测试结果发现以十二烷基苯及十二烷基苯和重烷基苯复配合成的Gemini表面活性剂对孤岛13XN712油样的界面张力可降低至10-4 mN.m-1。同时发现磺化试剂用量增加会使界面张力上升,表面活性剂加入量也不宜少于0.3%。In order to research how Gemini Surfactants by different condition synthesis and concentration of it effect interfacial tension of crude oil, Anionic Gemini was synthesized with heavy alkylbenzene and dodecylbenzenz, and then interfacial tension of crude oil was examined by salt solution of Gemini Surfactants. The result identified Gemini Surfactants can decrease the interfacial tension of island 13XN712 crude oil to 10^-4 mN-m^-1. Adittional, increasing amount of sulfonating agent could increase interfacial tension, and percentage of surfactant content is not less than 0.3 % when interfacial tension of crude oil was examined.
