摘要
体系由水或人工海水／煤油／表面活性剂（ＡＳ，ＣＴＡＢ，ＢＲＩＪ３５）／助表面活性剂（正丁醇）构成。研究４０℃时各表面活性剂、油及醇含量和海水盐度对微乳形成的影响。结果表明：３种表面活性剂中ＣＴＡＢ最易于形成微乳，在含煤油量≤５０％时皆可与纯水或海水形成Ｏ／Ｗ、Ｗ／Ｏ和双连续结构的３种形式微乳区；对于ＡＳ，这种微乳连续区仅在含煤油≤２５％时出现；而对于ＢＲＩＪ３５，只在含煤油１０％时才出现。随含油量增加，各表面活性剂体系其微乳区域面积分数皆明显减少。随海水盐度增加，各表面活性剂体系微乳区域面积分数减少。各体系中当醇与表面活性剂重量比小于０．７时不易形成微乳。
The phase diagrams are constructed for the water(of artificial seawater)/kerosene/surfactant(AS or CTAB or BRIJ35)/cosurfactant(n butanol) at 40℃. The influence of the surfactant type,oil or alcohol content and salinity in seawater on the the microemulsion formation was studied. The results show that the conditions of the surfactant CTAB and the mass ratio of alcohol/surfactant>0.7 are the most suitable for the microemulsion formation obeying Bansal Rule. The microemulsion containing CTAB has the most content of water. The microemulsion regions diminsh as the oil content increases,and that these regions decrease as the salinity increases. The total surface of microemulsions is CTAB>BRIJ35>AS for these three surfactant systems.
