Synthesis of Glycerol-Based Pyridinium Surfactants and Appraisal of Their Properties
beta-Bromo glycerol monoethers, when heated with pyridine at 100 degrees C for 10 h, gave a new glycerol-based pyridinium cationic surfactant, 1-(1-(2,3-dihydroxypropoxy)alkane-2-yl)pyridinium bromide (6a-10a)/1-(2-(2,3-dihydroxypropoxy)alkyl)pyridinium bromide (6b-10b) in a yield of 60%-70%. The surface properties and biocompatibility of these cationic surfactants has been determined and compared to tetradecyl trimethyl ammonium bromide (10) and cetyl pyridinium bromide (11).
