摘要：

Novel iminium compounds namely p-benzylidene benzyldodecyl iminium chloride (I), p-benzylidene benzylhexadecyl iminium chloride (II), p-benzylidene benzyloctadecyl iminium chloride (III) were prepared and characterized using FTIR, H-1-NMR and mass spectroscopy. The surface properties such as surface and interfacial tension, and biological activity of these surfactants were investigated. The surface parameters including critical micelle concentration, maximum surface excess, and minimum surface area. Efficiency and effectiveness were calculated, as well as free energies of micellization and adsorption. The prepared cationic surfactants exhibit a better biological activity than the used reference cetyl trimethyl ammonium bromide.
