摘要：A novel double-tailed cationic surfactant, N,N'-didodecylacetamidinium bicarbonate, was prepared by reacting dimethylacetamide dimethyl acetal with dodecylamine, followed by reacting with dry ice. MSD, FTIR, H-1 NMR, C-13 NMR, 2D-NMR were used to confirm its structure. The surfactant reduced the surface tension of pure water to 24.7 mN m(-1) and its critical micelle concentration was 8.75 x 10(-5) M. Formation of vesicle was also observed. (C) 2008 Elsevier B.V.
