油酸/氨水-醇-汽油-水微乳体系拟三元相图的分析

Analysis on the phase diagrams of pseudo-tricomponent of oleic acid/ammonia-gasoline-alcohol-water microemulsion system

制备了油酸 /氨水 汽油 醇 水微乳液系列 ,并采用拟三元相图对此微乳体系进行了研究。结果表明 ,助表面活性剂醇的种类对微乳汽油的微乳区面积及水最大增溶量具有很大影响 ,其中正丁醇体系的微乳区面积及水的增溶量最大。

The phase diagrams of pseudo-tricomponent of microemulsions consisting of oleic acid/ammonia-gasoline-alcohol-water were plotted, and the properties of this microemulsion system were discussed. It was found that the size of microemulsion regions and maximum water content of microemulsion were related to the kinds of alcohols, in which the n-butanol had the largest size of microemulsion regions and maximum water content of microemulsions. In addition, with the content of gasoline and environmental temperature increased, the size of microemulsion regions and maximum water content of microemulsions decreased.
