| 摘 要： | 维生素Ｃ（ＶＣ）能提高表面活性剂十六烷基三甲基溴化铵（ＣＴＡＢ）在水中的溶解度，具有助溶作用；且能提高ｎ－Ｃ５Ｈ１１ＯＨ在Ｏ／Ｗ微乳液中的增溶量和水在Ｗ／Ｏ微乳液中的增溶量，Ｏ／Ｗ与Ｗ／Ｏ微乳液区域同时扩大，具有助溶－增溶作用。ＶＣ的助溶作用与助溶－增溶作用均具有一定的选择性，只对阳离子表面活性剂ＣＴＡＢ体系有效，ＶＣ助溶－增溶作用的机理是同时增加Ｗ／Ｏ和Ｏ／Ｗ微乳液的稳定性和层状液晶向双连续结构

| Abstract: | Vitamin C is found to show hydrotrope action and enhance the aqueous solubility of surfactant CTAB it also show the hydrotrope-solubilization action to increase the solubilzed amount of n-C5H11OH in O/W microemulsion and that of water in W/O microemulsion. Both action of VC are selective so that they can only be effective in cationic surfactant CTAB system. The mechanism of the hydrotrope-solubilization action of VC is in fact to increase the stability of W/O and O/W microemusion and the structural transition from the lamellar liquid crystal phase to the bicontinuous structure. |
