中文摘要：
以Winsor相态图法和拟三元相图法研究了自制的3种不同链长烷基芳基磺酸盐在多组分体系中形成的微乳液的性质,并考察了分子结构、无机盐和短链醇等的影响.结果表明,无机盐浓度的增加导致表面活性剂/正丁醇/正辛烷/NaCl/水形成的微乳液体系在一定温度下发生由WinsorⅠ→WinsorⅢ→WinsorⅡ型转变;随着烷基芳基磺酸盐分子的长烷基链碳原子数的增加,耐盐能力减弱,增溶能力提高;随着醇碳链的增大,微乳区面积先增大后减小.当烷基芳基磺酸盐分子结构固定时,最大微乳液区域醇的选择依据符合Bansal理论.醇的链长一定时,随着烷基芳基磺酸盐分子的长烷基链碳原子数的增加,微乳液的区域变小.
英文摘要：
The properties of microemulsion formed by three alkyl aryl sulfonates（synthesized in the laboratory） in the multi-component systems were investigated by Winsor phase diagram and pseudo-ternary phase diagram methods.The influences of molecular structure,inorganic salt and short chain alcohol on these microemulsion properties were discussed,respectively.The results show that as the concentration of inorganic salt increases,the surfactants/n-butanol/n-octane/NaCl/water microemulsion systems transform from WinsorⅠ to Winsor Ⅲ and then to WinsorⅡ at certain temperature.With the increase of the number of long alkyl carbon atoms in alkyl aryl sulfonate molecule,the salt-toleran ability decreases but the solubilization capacity increases.With the increase of carbon atom number of the alcohol,the area of microemulsion region increases first and then decreases.When molecular structure of alkyl aryl sulfonate is fixed,the choice of alcohol is based on Bansal theory for the biggest microemulsion region.When the chain length of alcohol is determined,with the increase of the number of long alkyl carbon atoms in alkyl aryl sulfonate molecule,the area of microemulsion region will decrease.
