Micellization and antimicrobial properties of N-alkyl-(2-hydroxypropyl)morpholinium bromides

New ionic-liquid cationic surfactants have been synthesized on the basis of alkyl (C9, C10, C12, C14) bromides and 1-(4-morpholinyl)-2-propanol. Surface activity and specific electroconductivity of aqueous solutions of the obtained surfactants have been studied by tensiometric and conductometric methods. Depending on the length of the alkyl chain, the values of critical micellization concentration (CMC), maximum adsorption (Гmax), area of minimal cross-sectional surface of polar group of the surfactant (Amin), adsorption efficiency (pC20), surface pressure (πCMC), binding degree of the counter-ion (β), changes of Gibbs free energies of micellization and adsorption processes (ΔGmic and ΔGad) have been determined. Antimicrobial properties of the synthesized ionic-liquid surfactants have been studied on the example of different bacteria and fungus. © 2021 Elsevier B.V.
