【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。更多还原

【Abstract】 The structure parameters of SDS/n-butanol/nheptane/water microemulsion system were calculated by dilution method.The radius of inner water droplet R_w,the effective radius of particle R_e,the thickness of interface l,the total number of particles N_d,the total interfacial area of dispersed phase A_d,the average aggregation number of surfactant were studied.The change of standard free energy ΔG⁰_c→i for alcohol to transfer from the continuous phase to the interfacial membrane was also calculated.更多还原
