十二烷基磺基甜菜碱与其它类型表面活性剂的相互作用

Interaction between dodecyl sulfobetaine and various type surfactants

通过测定两性表面活性剂十二烷基磺基甜菜碱(SB12)与非离子表面活性剂TritonX100(TX)、阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)、阴离子表面活性剂十二烷基硫酸钠(SDS)混合溶液的表面张力及理论计算,探讨了它们之间的相互作用,从而为两性表面活性剂的复配应用提供了有价值的基础数据.

Surface tension measurements were carried out for mixed systems of dodecyl sulfobetaine (SB12) and Triton X-100, SB12 and hexadecyltrimethylammonium bromide (CTAB), SB12 and sodium dodecyl sulfate (SDS), respectively. Their molecular interaction parameters in the mixed micelles and mixed monolayers at the water/air interface were evaluated from the results of surface tension and critical micelle concentration(cmc). The results provide important information on the application of mixed surfactant systems.
