研究了以癸烷为油相的十一烯酸癸胺正负离子表面活性剂体系对水的加溶作用。结果表明此体系在一定组成范围内可以形成均匀透明的反胶团或反相微乳液。升高温度和添加酸、碱、盐可以使形成反胶团或反相微乳的组成范围扩大。在正负离子表面活性剂中加入离子型表面活性剂、特别是负离子型表面活性剂,也有类似的作用。

The solubilization of water in undecenoic acid-decyl amine/decane system has been investigated. A uniform and transparent liquid phase (L2, reversed micellar phase or reversed microemulsion) can be formed in a range of composition. The increase of temperature or addition of acid or alkali or salt enlarged the L2 area in phase diagram. Addition of ionic surfactants, espcially anionic surfactants, into the catanionic surfactant systems has similar effect.

Key words: ACIDUM UNDECYLENDCUM P, SURFACTANTS, MICROEMUSION, PHASE DIAGRAM
