A new method for the preparation of new heterocyclic amine surfactants based on sulfobetaines is proposed. Interfacial activities of the surfactants obtained in aqueous solution were studied by surface tension measurements. The critical micelle concentration, surface excess concentration, minimum area per surfactant molecule, and standard Gibbs energy of adsorption were determined. The adsorption properties
提出了一种新的基于磺基
甜菜碱的杂环胺表面活性剂的制备方法。通过表面张力测量研究了在
水溶液中获得的表面活性剂的界面活性。确定了临界胶束浓度,表面过量浓度,每个表面活性剂分子的最小面积和标准吉布斯吸附能。这些化合物的吸附性能在很大程度上取决于烷基链的长度。烷基链长也会影响新型表面活性剂的
生物学特性,从而决定了最低抑菌浓度和抑菌生长区的大小。该化合物具有很高的抗菌活性。
