Abstract: | A series of novel iminium surfactants were prepared through quaternization of different prepared fatty Schiff bases with benzyl chloride. The chemical structures were confirmed using FTIR, 1H-NMR and mass spectroscopy. The surface properties and biological activity of these surfactants were investigated. The surface parameters including critical micelle concentration (CMC), maximum surface excess (Γmax) and minimum surface area (A min), Efficiency (PC20) and Effectiveness (πCMC) as well as the free energy of micellization ( $ Updelta G_{text{mic}}^{text{o}} $ ) and adsorption ( $ Updelta G_{text{ads}}^{text{o}} $ ) were calculated. It was found that the prepared compounds have good surface and biological activity. |
