摘　　要：测试了 Fe SO4水溶液 /十二烷基磺酸钠 (SDS) +异戊醇 /二甲苯准三元体系的电导率与 SDS的含量 P(w/ % )、异戊醇与 SDS的质量比 Km 及水与 SDS的摩尔比 R三个结构参数的关系 ,并建立了它们的反相微乳液相图。系统地研究了体系的组成 ,如异戊醇和 SDS的质量比 Km、Fe SO4 溶液的浓度和 p H值、MMA的加入和温度 (T)对其反相微乳液相图的影响。结果表明准三元体系在形成反相微乳液的过程中 ,σ随 Km降低和 P增加而增大 ,随 R增大表现出明显的阈渗效应 ,发生阈渗效应的临界 R值为 4 ,远小于文献 [1,2The conductivity ( σ ) of the pseudo ternary system FeSO 4 aqueous solution/SDS + isopentanol/xylene was tested as functions of such composition parameters as P (concentration of SDS), K m (cosurfactant surfactant mass ratio), R (water SDS molar ratio); and the inverse microemulsion phase diagrams were established in various conditions. The influencing factors such as K m, concentration and pH of FeSO 4 aqueous solution, the temperature of experiment, addition of methyl methacrylate on inverse microemulsion phase diagram for the pseudo ternary system were studied. The results indicated that during the process of forming an inverse microemulsion, σ of the pseudo ternary system increased with both decreasing Km and increasing P. σ showed obvious threshold effect with increasing R , while the critical value is 4, which is far less than 12 or 15 reported in the literature.
