摘　　要：在40℃下,用ε-β"鱼状"相图法研究了阴离子表面活性剂十二烷基磺酸钠(十二烷基硫酸钠、十二烷基苯磺酸钠)/烷烃/脂肪醇/盐水微乳液体系的相行为和增溶能力,测定了亲水-亲油平衡界面膜的组成.结果表明,阴离子表面活性剂亲油基体积越大、油相碳链越短、醇的碳链越长、NaCl的浓度越高,微乳液的增溶能力越强.The phase behavior and solubilization of the microemulsion formed by sodium dodecyl sulfonate（sodium dodecyl sulfate,sodium dodecyl benzene sulfonate）/alcohol/ alkane/brine have been studied with ε-β-fishlike phase diagram at 40 ℃.The composition of the hydrophile-lipophile balanced interfacial layer is determined.The solubilization of the microemulsion system has been discussed based on the ε-β-fishlike phase diagram.The smaller the oil molecule,the longer the alcohol chain length,and the higher the NaCl concentration in water,the stronger the solubilization of the microemulsion system.
