二组分有机混合物在Winsor Ⅲ型微乳液中的增溶行为
Solubilization behavior of binary organic mixtures in Winsor type Ⅲ microemulsions
摘要
Abstract
Winsor type Ⅲ microemulsions were prepared using sodium dodecyl sulfate (SDS) as surfactant,n-butanol as cosurfactant,NaCl as inorganic salt adjuvants for different organic mixtures (binary mixtures of n-hexane,cyclohexane,toluene or n-octane).The gas chromatography was used to determine the organics content in the excess oil phase of Winsor type Ⅲ microemulsion.The influences of surfactant and NaCl concentrations,as well as the composition of organic mixtures were studied.The results show that the organic compositions in the excess oil phase and in the initial organic mixtures are different at different organic ratios when using binary mixtures of n-hexane,cyclohexane,toluene or n-octane to prepare the Winsor type ⅢI microemulsions at different surfactant concentrations (or mass ratios),which means the selectivity exists during solubilization.It is also found that smaller molecules having a slight polarity and those having higher molar solubilization ratio are preferentially solubilized.For the toluene-octane microemulsion systems,the increase of salinity and decrease of surfactant concentration can both benefit the solubilizing selectivity of toluene.关键词
