摘要
阳离子表面活性剂CTAB在微乳领域有广泛的应用。以CTAB为表面活性剂，分别将几种不同烷烃作为油相、几种不同醇作为助表面活性剂制备反相微乳体系，对微乳体系增溶纯水和增溶盐溶液时的相行为进行了研究。结果表明，当体系的水相为纯水或盐溶液时，正庚烷作为油相、正丁醇作为助表面活性剂使体系有最佳的增溶效果。
CTAB as a cationic surfactant has been widely applied in the field of microemulsion. In this paper, several microemulsions with CTAB as surfactant, different alkyls as oil phase and different alcohols as cosurfactant were prepared. The phase behavior of W/O microemulsions with pure water and salt water as water phase were discussed. The results show that no matter the water phase was pure water or salt water, the microemulsion system exhibits best performance when the oil phase is heptane and the cosurfactant is butanol.
