摘　　要：全氟辛酸钠(OBS)/十六烷基三甲基溴化铵(CTAB)-正丁醇/正丙醇-油-盐水体系能形成多相微乳液,本文应用正交试验设计寻找了最佳中相微乳液体系组成,然后系统地研究了含盐量、表面活性剂总浓度,醇总浓度,油的种类对该体系中相微乳液的形成,相态和其特性参数的影响.并且应用红外光谱对微乳液的微观结构进行了测定.最后还对碳氢表面活性剂和碳氢/碳氟表面活性剂复配体系进行了比较.本文结果对三次采油和日用化工等领域的应用以及对理论研究都具有重要的意义.Sodium perfluorooctanoate / cetyltrimethylammonium bromide, n - propyl alcohol/ butyl alcohol, octane and brine can form middle phase microemulsion. Its optimum components were found by using perpendicular experiment. The effect of salinity, concentration of surfactants and alcohol, kinds of hydrocarbon to the formation and characteristics of the middle phase microemulsion have also been investigated. Microstructure of the microemulsion was determined by infrared spectrum. The OBS/CTAB system was compared with CTAB and AOT/CTAB systems. The results are of importance to practical and theoretical research.
