  ABSTRACT: A homologous series of cationic surfactants were synthesized and characterized by spectral studies, mass, IR, 1H NMR, 13C NMR, 2D NMR and elemental analysis. The surface activities of these amphiphiles were measured, including surface tension (γ), critical micelle concentration (CMC), effectiveness (pcmc), efficiency (PC20), maximum surface excess (Γmax) and minimum surface area (Amin) at 25℃. Adsorption and micellization free energies of these amphiphiles in their solutions showed a good tendency towards adsorption at the interfaces. The synthesized amphiphiles showed good antimicrobial activity.
