用Winsor相图研究了十二烷基磺酸钠(AS)/正丁醇/烷烃/NaCl水溶液体系中相微乳液的相行为。结果表明,随醇浓度的增加,四元体系发生由水包油(O/W)型经中相微乳液(B.C.)到油包水(W/O)型微乳液的转变;表面活性剂浓度越大,得到的中相微乳液体积越大;形成中相微乳液时需要醇的量增加;中相微乳液形成和消失时对应的单位质量表面活性剂需要的醇量随表面活性剂浓度的增加而减小。本文研究了不同碳链长度的烷烃、脂肪醇和盐溶液对微乳液相行为的影响。
The phase behavior of phase microemulsion in sodium dodecyl sulfate (AS) / n-butanol / alkane / NaCl aqueous system was studied by Winsor phase diagram. The results showed that with the increase of the alcohol concentration, the transition from oil-in-water (O / W) through the microemulsion (W / O) to the water-in-oil The larger the volume of the medium-phase microemulsion obtained, the higher the amount of alcohol required to form the mid-phase microemulsion, and the amount of alcohol required per unit mass of the surfactant at the time of formation and disappearance of the mid-phase microemulsion varies with the surfactant concentration Increase and decrease. In this paper, the effects of alkanes, fatty alcohols and salt solutions with different carbon chain lengths on the phase behavior of microemulsion were studied.
