摘要(Abstract)：

【目的】分析温度对季鏻盐离液体微乳液相行为的影响规律。【方法】以季鏻盐离子液体为非极性相,水为极性相,TX-100/正丁醇为表面活性剂,构建5种微乳液体系,绘制拟三元相图、测定流变特性。【结果】高温有利于四丁基三氟乙酸膦([P_(4444)]CF_3COO)、三丁基辛基溴化膦([P_(4448)]Br)形成微乳液,低温利于四丁基四氟硼酸膦([P_(4444)]BF_4)、三丁基辛基三氟乙酸膦([P_(4448)]CF_3COO)、三丁基辛基四氟硼酸膦([P_(4448)]BF_4)形成微乳液。其中[P_(4444)]CF_3COO和[P_(4448)]Br具有低临界溶解温度(LCST)的相转变行为,[P_(4444)]BF_4、[P_(4448)]CF_3COO和[P_(4448)]BF_4具有高临界溶解温度(UCST)的相转变行为。5种季鏻盐离子液体微乳液的黏度均随温度升高而显著下降,流体类型由假塑性流体趋向于牛顿流体。【结论】温度是影响季鏻盐离子液体微乳液相平衡的重要因素。
