摘要：

绘制了35, 45, 55, 65 ℃下, 十二烷基硫酸钠(SDS)/正戊醇-环己烷-水体系的拟三元相图. 分析了温度对相图和微乳液区域的影响. 结果表明, 温度对油包水(W/O)反相微乳液区域大小有影响, 但影响较小, 温度对水包油(O/W)微乳液区域的影响较大, 且随温度的增加, 区域增大. 电导率曲线与相图吻合很好, 并用电解质溶液理论进行了解释.

关键词: SDS/正戊醇-环己烷-水拟三元相图, 微乳液, 电导率

Abstract:

Sodium dodecyl sulfate(SDS)/n-pertanol-cyclohexane-water psudo ternary phase diagrams at 35, 45, 55, 65 ℃ were studied. Pseudo ternary phase diagrams agree well with measure result of conductivity. The relationship between peudo ternary phase diagrams and conductivity was discussed via electrolyte theory. The relationship between peudo ternary phase diagrams and temperature was studied.The results show that the area of W/O microemulsion changes little with temperature and that the area of O/W microemulsion changes large with temperature.The result is very use to nano particle preparation in microemulsion system.

Key words: SDS/n-pertanol-cyclohexane-water peudo ternary phase diagram, Microemulsion, Conductivity
