摘要
采用自制的功能离子液体1-(胺乙基)-3-丁基咪唑六氟磷酸盐([NH_2ebim][PF6]),制备了水/[NH_2ebim][PF_6]/Triton X-100/正丁醇/环己烷微乳液体系,通过动态光散射技术测定微乳液的粒径分布和分散相浓度,通过电导率仪测定体系电导率的变化,由这两种分析方法确定微乳液类型,微乳液类型被分为表面活性剂与水的互溶相包油型(O/S+W)和水包油型(O/W),并绘制出拟三元相图;通过耗散动力学(DPD)模拟不同水含量时微乳液体系中的聚集行为,模拟结果呈现出的微乳液类型与实验测定分析结果一致,证明了相图绘制的正确性;文中还考察了Triton X-100与正丁醇的比例对微乳液区域的影响,实验结果表明,随着Triton X-100与正丁醇的比例增加微乳液区域增大。
Microemulsion with self-made task-specific ionic liquid[NH_2ebim][BF6],[NH_2ebim][BF_6]/H_2 O/Triton X-100/n-butonal/cyclohexane microemulsion has been prepared.Microemulsion types have been determined by the analysis of electrical conductivity and the dynamic light scattering technique,and microemulsion region is divided into O/（ S＋W） and O/W microemulsion.The ternary phase diagrams has been drawn according to the experimental results.The aggregation behavior of water in the microemulsion system was studied by dissipative particle dynamics（ DPD）. The results of simulation are agree with those of experiment.The effects of the microemulsion region on the proportion of Triton X-100 and n-butonal were investigated.Experimental results show that the region of microemulsion increases with the increase of the proportion of Triton X-100 and n-butonal.
