摘要
研究了双生表面活性剂α-磺基硬脂酸聚乙二醇双酯钠盐/正丁醇/正辛烷/水微乳液体系的制备及稳定条件,绘制了其微乳液的拟三元相图,探讨了不同碳链长度的醇在不同温度下对微乳状液的形成和稳定性的影响,并讨论了0.1mol/LKCl、NaOH、HCl溶液对该微乳液体系性能的影响.结果表明:在一定温度范围内,温度的升高和醇碳链中碳原子数的增加均有利于W/O型微乳液的形成和稳定;电解质溶液一般使微乳区域缩小,且以电解质溶液为分散介质与以纯水为分散介质的微乳液的电导率基本上相同.
Microemulsion of gemini surfactant sodium α-sulphonated stearic acid polyethyleneglycol diester,butanol,octane and water system and its stability were studied.Phase diagrams of the microemulsion system were drawn.The influence of different carbon chain lengths of alcohol under the different temperatures to form the microemulsion and its stability were discussed,in addition to the influence of 0.1mol/LKCl,NaOH and HCl solutions to the microemulsion system.The results show that,in certain temperature range,in...
