摘要 用表面张力法研究了288K时6-OTs-β-CD与十六烷基三甲基氯化铵(CTAC)形成的超分子包络物及CTAC的表观临界胶束浓度(CMC*)与6-OTs-β-CD浓度的关系。研究发现,CTAC与6-OTs-β-CD可形成包结比为2∶1的超分子包络物,包络物表观稳定常数为2.0×103L/mol。表面活性剂的表观临界胶束浓度(CMC*)与环糊精的浓度呈较好的线性关系。 The relations of supramolecular inclusion complex of 6-OTs-β-CD with CTAC and apparent critical micelle concentrations （CMC^＊） of CTAC to concentrations of 6-OTs-β-CD at 288K were studied by surface tension measurement. The results showed that supramolecular inclusion complex with stoi- chiomtetry of 2 ： 1 in aqueous solution can be formed by 6-OTs-β-CD with CTAC. Apparent formation constant of the inclusion complex is 2. 0 × 10^3 L/mol. CMC^＊ of the surfactant varied linearly with CD concentrations.
