three AOT based ionic liquids have been investigated in aqueous medium in the presence of different concentrations i.e. (0.04, 0.08, 0.12, 0.16) mM of sodium bis(2-ethylhexyl) sulfosuccinate (NaAOT) at different temperatures (298.15, 308.15, 318.15) K. The AOT based ionic liquids have been successfully synthesized by replacing the cation of sodium bis(2-ethylhexyl) sulfosuccinate (NaAOT) with various
在不同浓度(0.04、0.08、0.12、0.16)mM双(2-乙基己基)磺基琥珀酸钠(NaAOT)存在下,在不同温度(298.15, 308.15, 318.15) K.通过用胆碱[Cho] +、四乙铵[TEA] +等多种药理活性阳离子代替双(2-乙基己基)磺基琥珀酸钠(NaAOT)的阳离子,成功合成了基于AOT的离子液体,和四丁基铵 [TBA] +. 通过评估各种热力学和表面活性参数(例如胶束化的标准自由能),已采用电导率和表面张力测量来了解它们的聚集行为。ΔG米0), 标准胶束化焓 (ΔH米0), 胶束化的标准熵 (Δ秒米0),表面压力在 厘米 (一种́¨厘米), 最大表面过量浓度 (Γ最大限度),表面活性剂单体在空气/水界面的最小面积 (一种分钟), 标准吉布斯吸附自由能 (ΔG广告0) 和平衡时表面的自由能 (G分钟秒)。
