用拟二元及拟三元相图法研究了醇醚糖苷(AEG30、AEG08)/醇/环己烷/水四组分微乳液的相行为,与烷基糖苷(APG)相行为作了比较,并用内聚能比(R比)理论作了解释。结果表明,拟二元体系,随着正丁醇质量分数的增大,APG、AEG08微乳液类型发生WinsorⅠ→Ⅲ(Ⅳ)→Ⅱ的转变,AEG30发生WinsorⅠ→Ⅲ(Ⅳ)→Ⅱ→Ⅳ→Ⅰ的转变,表面活性剂EO链越长,发生WinsorⅠ→Ⅲ(Ⅳ)转变所需最小醇质量分数越大;随着正戊、己醇质量分数的增大,AEG30微乳液类型发生WinsorⅠ→Ⅲ(Ⅳ)→Ⅰ转变。拟三元体系,随着表面活性剂及正丁醇(S+A)质量分数的增大,AEG微乳液类型也发生WinsorⅠ→Ⅲ(Ⅳ)→Ⅱ的转变,对于APG只出现WinsorⅡ、Ⅳ;油水比对AEG30/正戊、己醇/环己烷/水微乳相行为有很大的影响。
The phase behavior of the alcoholic glycosides (AEG30, AEG08) / alcohol / cyclohexane / water microemulsion was studied by means of quasi-binary and quasi-ternary phase diagram methods and compared with that of alkyl glycoside (APG) , And is explained by the cohesive energy ratio (R ratio) theory. The results showed that WinsorⅠ → Ⅲ (Ⅳ) → Ⅱ transition occurred in the APG and AEG08 microemulsions with the increase of the n-butanol mass fraction in the quasi-binary system. WinsorⅠ → Ⅲ (Ⅳ) → Ⅱ → Ⅳ → Ⅰ, the longer the EO chain of surfactant, the smaller the minimum alcohol mass fraction required for the WinsorⅠ → Ⅲ (Ⅳ) transformation to occur is. With the increase of the mass fraction of n-pentanol and hexanol, WinsorⅠ → Ⅲ (Ⅳ) → Ⅰ transition. In the quasi-ternary system, the WinsorⅠ → Ⅲ (Ⅳ) → Ⅱ transition also occurred in AEG microemulsion with the increase of surfactant and n-butanol (S + A) The ratio of oil to water has a great effect on the behavior of AEG30 / n-pentanol, hexanol / cyclohexane / water microemulsion.
