摘要
研究了以甲酰胺为极性相,正辛烷为油相,以脂肪醇聚氧乙烯(3)醚(AEO3)为表面活性剂形成的非水微乳液相行为。以甲基蓝(MB)和甲基橙(MO)为探针,利用探针在溶液、胶束、反胶束等不同极性环境下吸收峰位置的变化,通过紫外-可见光吸收光谱研究了该非水微乳液相区的微观结构,确定了该体系可以形成以甲酰胺为分散相,正辛烷为连续相的油连续型微乳液。
The oil-continuous microemulsion phase behavior formed by formamide(polar phase),n-octane(oil phase),tri(ethyleneglycol)monododecyl ether(AEO3) was investigated.Using the methyl orange(MO) and methylene blue(MB) as Absorption probes,the microstructure of nonaqueous microemulsions was probed with UV-vis spectroscopy measurements while the Absorption maximum is changed with the polarities of pure solvents,micelles and reverse-micelles systems.The results indicated that an n-octane continuous structure with formamide nano-droplets formed in the formamide/AEO3/n-octane system.
