| 摘 要： | 研究了以NPE4．2和NPE10混合壬基酚聚氧乙烯醚为表面活性剂的W／O型微乳液的相行为，以最大增溶水(溶液)为参数，用电导法研究了混合表面活性剂配比、用量、助表面活性剂的用量、不同阳离子水溶液和温度对W／O型微乳液的影响，实验表明：当NPE4．2：NPE10为1．2：1，(S A)：O＝3：7附近，该体系具有最大的增溶水量。当用其它溶液代替水或使体系的温度升高时，拟三元体系的增溶液量曲线与增溶水量曲线相似，但其单相区的面积有不同程度的减小。

| Abstract: | The phase behavior of W/O microemulsion employed blend NPE4.2 and NPE10 as surfactants was studied. The influence of blend surfactant proportion, surfactant dose co-surfactant dose, various cations and temperature on W/O microemulsion phase behavior was examined by way of electric conductivity with the maximum dissolve water (solution) being the target. Experiments indicated that as the NPE 4.2 :NPE 10 is about 1.2:1 and (S+A):O is about 3:7, the maximum dissolve water was acquired. When the water was substituted by other cations solution or the temperature was increased, the effect to the microemulsion was resemble to the water. But the domain of W/O microemulsion is decreased. |
