首次报道在短链脂肪醇/水溶剂中十二烷基硫酸钠和辛基三甲基溴化铵混合体系由沉淀转化为囊泡，并出现表面活性剂双水相的新现象，以期探索正负离子表面活性剂混合体系研究的新途径。

In this work a way of transition from precipitation to vesicle through addition of short chain fatty alcohol was developed. By adding 7%～14%(V/V) of 1-propanol or 10%～21%(V/V) of ethanol at 30℃ the precipitation of catanionic surfactant was dissolved to give a two liquid-phase system. The photography of TEM demonstrated that vesicles exist in the lower phase. The phenomenon of double refraction was found in the upper phase.
