亚油酸乙酯微乳成乳条件的研究

 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。

The formation and characterization of microemulsion systems containing water, aerosol-OT, alcohol, ethyl linoleate

OBJECTIVE: To study the preparing conditions, the phase behaviours and the stability of microemulsion. METHODS: The ethyl linoleate used was investigated as oil. Aerosol-OT was investigated as surfactant and three short chain alcohols (n-propanol, n-butanol, n-pentanol) were investigated as cosurfactants. Microemulsion was prepared by titrating the compounds of oil, surfactant and cosurfactant with distilled-water. According to the above results, pseudo-ternary phase diagrams were constructed. The factors influencing the stability were investigated such as cosurfactant, surfactant, etc. RESULTS: Stable microemulsion was made. CONCLUSIONS: Alcohols affect the phase behaviours. Alcohols, mixing ratio of alcohol, and surfactant (Km) are the factors affecting the stability of microemulsions.
