本文报道了多元醇(1,2-丙二醇,乙二醇,甘油)对于水-已烷-十二烷基磺酸钠-正已醇体系相性质的影响。发现上述各添加剂在适当的正已醇/十二烷基磺酸钠比例下均可扩大O/w型微乳区域的面积;以及提高正已烷在体系中的增溶量,其中尤以1,2-丙二醇作用最显著。形成O/w型微乳状液的条件比较苛刻,而且其机理也可能与w/O型有所不同。从应用角度,我们希望知道如何扩大O/w型微乳区域的面积,以及提高油在水中的增溶量;从理论角度,试图对O/w型微乳生成机理进行探讨。
This paper reports the effects of polyols (1,2-propanediol, ethylene glycol, glycerol) on the phase properties of a water-hexane-sodium dodecyl sulfate-n-hexanol system. The above additives were found to expand the area of the O / W microemulsion region at the appropriate n-hexanol / sodium dodecylsulfonate ratio, and to increase the amount of n-hexane solubilized in the system, with 1 , 2-propanediol the most significant role. O / w microemulsion to form the more demanding conditions, and its mechanism may also be different w / O type. From an application point of view, we hope to know how to enlarge the area of O / W microemulsion region and increase the amount of oil in water. From a theoretical point of view, we try to discuss the formation mechanism of O / W microemulsion.
