| 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。

| Abstract: | 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 ... |
