摘　　要：采用醇度扫描和盐度扫描配制十二烷基硫酸钠(SDS)-正丁醇-煤油-水微乳液,考察酸碱性对微乳液形成的影响。实验结果表明,酸性对SDS-正丁醇-煤油-水微乳液体系的影响显著,H+浓度越高制备微乳液所需的醇用量越少;阳离子对微乳液形成的作用强度高低的顺序为H+>K+>Na+;碱性对微乳液体系的形成无特殊影响;在酸性条件下形成WinsorⅢ型微乳液后,再加入NaOH,体系可转变为WinsorⅠ型微乳液,进一步加入NaOH,体系的油溶性增强,再转换为WinsorⅢ型或WinsorⅡ型微乳液。The influences of acidity and alkalinity on sodium dodecyl sulfate （SDS）-n-butanol- kerosene-water （including electrolytes） microemulsion system were investigated using salinity scanning and n-butanol scanning. The results showed that the influence of acidity on the microemulsion system was significant. The higher the H ＋ concentration was, the less the needed n-butanol amount in preparation of the microemulsion was. The strength order for the cationic influence on the microemulsion was H ＋ 〉 K＋ 〉 Na ＋. Alkalinity had no distinct influence on the microemulsion system. HCl was used as electrolyte to prepare Winsor III type microemulsion, and then NaOH was added into the system, which led to conversion of the Winsor III type microemulsion system to WinsorItype system. Through further addition of NaOH, Winsor III orIItype microemulsion system could be formed.
