【摘要】 用ε-β"鱼状"相图法研究了离子液体表面活性剂溴化1-十二烷基-3-甲基咪唑(C12mimBr)与十二烷基硫酸钠(SDS)复配形成的SDS-C12mimBr/正丁醇/正辛烷/5%NaCl水溶液微乳液体系的相行为和增溶性能。阴、阳离子表面活性剂以不等摩尔比复配,由于强烈的静电作用,产生显著的协同作用,使复配体系的增溶性能比单一表面活性剂得到了显著的提高。更多还原

【Abstract】 The phase behavior and solubilization of the microemulsion system surfactant-like ionic liquids 1-dode-cyl-3-methylimidazolium bromide (C12mimBr)-sodium dodecyl sulfate (SDS)/n-butanol/n-octane/5% NaCl solution have been studied with ε-β-fishlike phase diagram method. The unequimolar composite of anionic and cationic surfactants could bring obvious synergism effect arise from the strong electrostatic interactions between the oppositely charged head groups, and make the solubilization of the microemulsion formed by mixed anionic and cationic surfactants more effective than the single surfactant system.更多还原
