中文摘要:
      以季铵盐类阳离子表面活性剂十八烷基三甲基氯化铵(OTAC)及十六烷基三甲基溴化铵(CTAB)微乳液体系为研究对象,考察了其对单一有机物和有机混合物(正辛烷、正十二烷-正已烷、正十二烷-正庚烷、正十二烷-正辛烷)的增溶性能,探究了 Winsor Ⅲ型微乳液最佳醇用量(A*)及最佳增溶参数(SP*)的变化规律。结果发现:两种阳离子表面活性剂微乳体系表现出相似的规律,即随着盐质量浓度的增加,SP*单调上升,A*单调下降;随着表面活性剂质量浓度的增加,A*持续增大,SP*先增大后减小。油相为二组分有机混合物的微乳体系A*和SP*仅与有机混合物等效烷基碳数(EACN)有关,与混合物的种类无关。将拟合所得二组分有机混合物的微乳体系A*和SP*与EACN关系式用于预测四组分混合有机物的A*和SP*,与实验值对比发现两者吻合较好,表明可以用所得函数关系式预测相近EACN范围内的A*和SP*。
英文摘要:
      Two kinds of microemulsion systems for quaternary ammonium salts surfactan, octadecyl trimethyl ammonium chloride (OTAC) and hexadecyl trimethyl ammonium bromide (CTAB) ,were studied on their solubilization properties for single organic compound and organic mixtures (n-octaneand binary mixtures of n-dodecane/n-hexane, n-dodecane/ n-heptane and n-dodecane/n-octane). The optimal alcohol dosage (A*) and the optimum solubilization parameter (SP*) of Winsor III microemulsions were studied. The results suggested that the two surfactant microemulsion systems showed similar patterns. With the increase of salinity, SP* increased monotonically and A*decreased monotonically. With the increase of surfactant concentration, A* increased, while, SP *increased first and then decreased. For the binary organic mixtures, the relationship between A* and EACN or SP* and EACN is the same no matter what is the components in the organic mixtures. The fitted equations for the binary organic mixtures were used in the prediction for quaternary organic mixtures. The predicted A* and SP* data coincided with the experimental values satisfactorily, which means that the obtained functional relationship can be used to predict A* and SP*in the similar range of EACN for different organic mixtures.
