油水比对阴离子型微乳液相行为的影响
|
摘要
微乳液由水、油、盐、表面活性剂及助表面活性剂组成,其相行为及增溶情况受各组分的影响。研究发现,在SDBS(SDS、SLS)/航空煤油/水/正丁醇/氯化钠体系中,随着NaCl含量的不断增多,微乳液体系发生Winsor Ⅰ型→Winsor Ⅲ型→Winsor Ⅱ型的相态转变。固定水的用量,通过油扫实验不断改变体系中的油水比,利用相图研究油水比对微乳液相行为的影响,并通过冷冻电镜对不同相态下微乳液的微观形貌进行了表征。随着油水比的增加,在低盐度下,体系由胶团溶液转变为Winsor Ⅰ型;而在高盐度下,体系发生由胶团溶液→Winsor Ⅱ型→Winsor Ⅲ型→Winsor Ⅰ型的相态转变。盐度一定时,微乳液的中相形成及消失所需的油量会随着表面活性剂浓度的增多而增多,且三种表面活性剂中,表面活性剂的增溶能力的大小顺序为SDBS>SDS>SLS,对煤油的敏感程度顺序为SLS>SDS>SDBS。
Micro-emulsion is composed of water, oil, salt, surfactant and co-surfactant. Its phase behavior and solubilization performance are affected by each component. It is found that in the SDBS(SDS, SLS)/aviation kerosene/water/n-butanol/NaCl system, with the increase of NaCl content, the phase inversed from Winsor Ⅰtype to Winsor Ⅲ type to Winsor Ⅱ type. The effect of oil-water ratio on the phase behavior of microemulsion was studied by phase diagram. The micromorphology of the micro-emulsion under different phase conditions was characterized by cryo-electron microscopy. With the increase of oil-water ratio, the system changed from micelle solutin to Winsor type Ⅰ under low salinity. While, at high salinity, with the increase of oil/water ratio, the phase inversed from Winsor Ⅱ type to Winsor Ⅲ type to Winsor Ⅰ type. When the salinity is constant, the amount of oil required for the formation and disappearance of the middle phase of the micro-emulsion will increase with the increase of surfactant concentration. In addition, among the three surfactants, the order of solubilization ability of surfactants is SDBS > SDS > SLS, and the order of sensitivity to kerosene is SLS>SDS>SDBS.
