目的：探索微乳的制备条件，考察微乳体系的相图行为及稳定性。方法：以亚油酸乙酯为油相，二辛基琥珀酸磺酸钠（ａｅｒｏｓｏｌＯＴ）为表面活性剂，短链醇（正丙醇、正丁醇、正戊醇）为助表面活性剂，用蒸馏水滴定上述３组分不同配比的混合物以制备微乳，绘出微乳体系的伪三元相图；考察助表面活性剂、表面活性剂等因素对稳定性的影响。结果：以适当的配比制得稳定的微乳。结论：醇对相图行为有影响。醇的种类，醇与二辛基琥珀酸磺酸钠的比值影响微乳的稳定性 Objective: To explore the preparation conditions of microemulsion and to investigate the phase behavior and stability of microemulsion system. Methods: Ethyl linoleate as the oil phase, sodium dioctylsuccinate sulfonate (aerosol  OT) as a surfactant, short-chain alcohols (n-propanol, n-butanol, n-amyl alcohol) Agent, titrating the mixture of the three components in different proportions with distilled water to prepare the microemulsion and plotting the pseudo-ternary phase diagram of the microemulsion system; and examining the influence of the co-surfactant, the surfactant and the like on the stability. Results: Stable microemulsions were prepared at appropriate ratios. Conclusion: Alcohol affects phase behavior. The type of alcohol, the ratio of alcohol to sodium dioctyl sulfosuccinate affected the stability of the microemulsion
