N-(1-Adamantyl)-N,N-dimethylamine was synthesized by Eschweiler-Clarke methylation reaction of 1-adamantine and formaldehyde in presence of excess formic acid firstly. Then five adamantane-based surfactants, including N-(1-adamantyl)-N,N-dimethyl-betaine, N-(1-adamantyl)-N,N-dimethyl- butyl-1-ammonium bromide, N-(1-adamantyl)-N,N-dimethyloctyl-1-ammonium bromide, N-(1-adamantyl)- N,N-dimethyldodecyl-1-ammonium bromide and N-(1-adamantyl)-N,N-dimethyl-hexadecyl-1-ammonium bromide were prepared via quaternarization reactions of N-(1-adamantyl)-N,N-dimethylamine with the sodium chloroacetate, 1-bromobutane, 1-bromooctane, 1-bromododecane and 1-bromohexadecane, respectively. The structures of products were identified by elemental analysis, IR, 1HNMR, etc.

Key words: adamantane, quaternary ammonium, surfactant, synthesis
