摘要
由非离子型表面活性剂、助表面活性剂（醇）、水和油形成微乳液，用拟三角相图中微乳区的面积确定形成微乳液的最佳条件．实验证明，油的碳原子数加上醇的碳原子数等于表面活性剂的碳原子数时为微乳液形成最佳条件。
The interrelation of carbon numbers was studied in microemulsions containing nonionic surfactant, n alcohol, n hydrocarbon and water by construction of pseduo ternary phase diagrams. Mixtures of the surfactant, alcohol and hydrocarbon were titrated at 30 ℃ with water to the points of turbidity and clarity to determine the microemulsion area. The total area of the microemulsion of different types for AEO 9, n alcohol, n hydrocarbon and water reached a maximum value when N O, carbon number of the oil, N O, carbon number plus that of the alcohol, N A, was equal to that of the AEO 9, N S( N S= N O+ N A). The results are discussed theoretically.
