摘要
用稀释法测定SDS/正丁醇/正庚烷/水体系W/O型微乳液的结构参数,求得不同ω(水和SDS的摩尔比)时体系的水内核半径Rw、颗粒有效半径Re、界面层厚度l、颗粒总数Nd、分散相所占总界面积Ad和平均聚集数-n。研究了不同水量时,醇从油连续相转移到界面层时自由能变化ΔG0c→i。
The structure parameters of SDS/n-butanol/n-heptane/water microemulsion system were calculated by dilution method. The radius of inner water droplet Rw, the effective radius of particle Re, the thickness of interface l, the total number of particles No, the total interfacial area of dispersed phase Ao, the average aggregation number of surfactant n^- were studied. The change of standard free energy △Gco→i for alcohol to transfer from the continuous phase to the interfacial membrane was also calculated.
