研究了烷基聚葡糖苷（APG）/正丁醇/环已烷/H2O 四组分微乳液体系的相行为,得到中相微乳液的“鱼状”相图.恒定γ值增大δ时,体系从下相微乳液（Winso Ⅰ型）和剩余油相的两相平衡,经中相微乳液（WinsorⅢ型、 剩余油相和水相的三相平衡,转变为上相微乳液（Winsor Ⅱ型）和剩余水相的两相平衡.从“鱼状”相图的位置和形状,计算得到了中相微乳液达亲水-亲油平衡时,体系的一些重要参数,如O点冲相消失,水油两相平衡）和E点（三相消失,单相形成）的组成（γo,δo）和（γe,δe）界面膜中APG和正丁醇的质量分数S1S,S2S,APG单体分子和正丁醇在环已烷中的溶解度S1,S2,平衡界面膜中APG和正丁醇在总组分中所占的质量分数C1和C2等.考察了不同醇类、不同水相和油相对相图、平衡界面膜组成及APG形成单相微乳液效能等的影响.发现使用长碳链的醇、小体积的油分子或加入无机盐,均有利于单相及中相微乳液的形成,并对此进行了解释.
The phase behavior of the alkyl polyglucoside (APG) / n-butanol / cyclohexane / H2O four-component microemulsion system was studied and the “fishlike” phase diagram of the middle-phase microemulsion was obtained. , The system was transformed from the phase equilibrium of the lower phase microemulsion (Winso Ⅰ type) and the remaining oil phase to the upper phase microemulsion (Winsor Ⅱ type) through the phase equilibrium of the middle phase microemulsion (Winsor Ⅲ type, residual oil phase and water phase) Type) and the remaining water phase.According to the position and shape of the “fish-like” phase diagram, some important parameters of the system, such as O-point red phase (Γo, δo) and (γe, δe), the mass fraction of APG and n-butanol in the interface membrane at points E (three phases disappear, single phase formation) The solubility of molecules and n-butanol in cyclohexane S1, S2, the balance of the mass fraction of APG and n-butanol in the total components C1 and C2, etc. Different alcohols, different aqueous phase and oil relative Phase diagram, equilibrium interface membrane composition and the formation of single-phase microemulsion APG performance, etc. It was found that the use of long-chain alcohol, a small volume of oil molecules or Inorganic salts, and are conducive to formation of a single phase microemulsion phase, and this is explained.
