摘　　要：用ε-β"鱼形"相图法研究了离子液体表面活性剂溴代-1-十六烷基-3-甲基咪唑(C16mimBr)/正丁醇/正辛烷/盐水微乳液体系的相行为和增溶能力,利用ε-β型HLB平面方程计算了亲水-亲油平衡界面膜的组成及相关物理化学参数。研究发现,水溶液中NaCl的质量分数越大,微乳液的增溶能力越强;固定阴离子浓度,改变阳离子的种类和电荷时,基本不影响C16mimBr形成微乳液的相行为和增溶能力,而固定同价态无机盐浓度,阴离子水化半径的越小,微乳液的增溶能力越强。The phase behavior and solubilization of the microemulsion system surfactant-like iomc hqulds 1- hexadecyl-3-methylimidazolium bromide （C16 mimBr）/n-butanol/n-octane/brine were studied with e - β- fish-like phase diagram method at 40℃ and an oil-to-water mass ratio of 1 ： 1. -The composition of the hydrophile-lipophile balanced interfacial layer was calculated with ε-β-HLB plane equation. It was found that the higher the concentration of sodium chloride and the shorter the. hydrated radius of the anions, the larger the solubilization power of the microemulsion. Fix the Cl- concentration and change the kinds and charge of cations, the phase behavior and solubilization of the microemulsion was little changed in this microemulsion system.
