摘要

Abstract

Micro-emulsion usually consists of water

oil

surfactants and co-surfactants

and each component has an effect on the phase behavior and solubilization of the micro-emulsion. When the surfactant in the micro-emulsion system is quaternary ammonium cationic Gemini surfactant

the surfactant mainly combines with the anions in the salt. With the increase of salt concentration

the phase transformation of Winsor I → Winsor Ⅲ → Winsor Ⅱ occurred

but the optimum salinity and salt width are different because of the type of salt. The effects of 5 different kinds of monovalent anions

including C

and Cl

on the phase behavior and solubilization of quaternary ammonium cationic Gemini micro-emulsion are researched by Winsor phase diagram. It is found that the effects of organic anions C

and I

on the phase behavior and solubilization of quaternary ammonium cationic Gemini micro-emulsion are most significant

and the effects of Br

and Cl

are less significant. Meanwhile

when the opt

imum solubilization is achieved

the amount of sodium benzoate is the least

indicating that the organic anion has stronger self-organization behavior with quaternary ammonium cationic Gemini surfactants.
