Surface and Biological Activity of Some Prepared Iminium Surfactants Based on Schiff Bases

Abstract

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, 1 H‐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 (Γ max ) and minimum surface area ( A min ), Efficiency (PC 20 ) and Effectiveness (π CMC ) as well as the free energy of micellization ( ) and adsorption ( ) were calculated. It was found that the prepared compounds have good surface and biological activity.
