摘要/Abstract

摘要： 绘制了CTAB/正丁醇-正辛烷-水和Al(NO₃)3(或Na2WO4)盐水拟三元体系的35℃相图.用电导法并结合电解质理论讨论了微乳液的微观结构,将整个微乳液单相区分为W/O微乳区、O/W微乳区和B.C.双连续区,并且用渗滤理论确定了一个分散相质点为W/O球状结构的反胶团微乳液区.

Abstract: The phase diagrams of the pseudo-ternary-component of CTAB/n-butanol-n-octane-water or brine[Al（NO₃）₃ or Na₂WO₄] systems were studied by dilution method. The microstructures of microemulsions were determined through conductance technique. Via percolation theory and electrolyte theory the single-phase regions of the microemulsions were delimited as W/O,O/W and bicontinuous microemulsion domains. In the W/O microemulsion regions we got a small domains（L′） in which the dispersed entities are of spherical form.

Key words: CTAB, Microemulsion, Pseudo-ternary-component phase diagram, Conductivity
