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 phase behavior of non-aqueous microemulsion with formamide as the polar phase, n-octane as the oily phase and fatty alcohol polyoxyethylene (3) ether (AEO3) as the surfactant was investigated. Methyl blue (MB) and methyl orange (MO) were used as probes to detect the changes of the absorption peak position of the probe under different polar environments such as solution, micelles and reverse micelles. The results of UV-Vis absorption spectra The micro-structure of the non-aqueous microemulsion phase region confirms that the system can form oil continuous microemulsion with formamide as the dispersed phase and n-octane as the continuous phase.
