Abstract:
A series of heterogemini imidazolium surfactants with two-methylene spacer groups ([Cm-2-Cnim]Br2, m, n=8, 10, 12, 14, 16; mn) have been synthesized and characterized by 1H NMR and ESI-MS spectroscopy. The effects of various reaction parameters, including stoichiometry, reaction temperature and time, were investigated. In addition, the surface activity study about heterogemini imidazolium surfactants was carried out and the influences of dissymmetric degree on the surface properties were also discussed.

摘要:
合成了一系列以两个亚甲基为联接基的杂双子咪唑表面活性剂([Cm-2-Cnim]Br2, m, n=8, 10, 12, 14, 16; mn). 用氢谱和质谱对其结构进行了表征. 探索了物料比、反应温度和时间对反应产率的影响. 对合成的杂双子咪唑表面活性剂的表面活性进行了研究,讨论了分子结构的不对称程度对表面活性的影响.
