The interaction parameters in the monolayer（βα）and the mixed micelles（βM）for each system were determined by surface tension measurement.There were synergisms in ability to reduce the surface tension,the efficiency of reducing surface tension and the formation of mixed micelles between octylpheno1polyoxyethylene and sodium dodecylbenzenesulfonate.Quantitative measurement of washing oil and solubilization showed that there were synergisms between octylpheno1polyoxyethylene and sodium dodecylbenzenesulfonate,and it also showed a synergistic effect in the ability of washing oil,but not in the solubilization.The ability of washing oil was strongest when concentration ratio of octylpheno1polyoxyethylene in the mixed surfactants was between 0.5and 0.8. 辛基苯酚聚氧乙烯醚 十二烷基苯磺酸钠 复配 剥离洗油 octylpheno1polyoxyethylene sodium dodecylbenzenesulfonate synergisms washing oil 10.14188/j.1671-8836.2010.05.009 TQ423 国家自然科学基金资助项目（20973129） 2010-05-01 2021-04-01 5 56
