A series of novel quaternary ammonium surfactants containing adamantane were designed and synthesized from 1-adamantanecarboxylic acid.The structures of target surfactants were confirmed by]H NMR,elements analysis and FTIR.Surface properties of these surfactants were investigated.Due to the lipophilicity of adamantane,the critical micelle concentration(CMC) and C_(20) values of the synthesized quaternary ammonium surfactants are lower than that of conventional quaternary ammonium surfactants.

The structures of the target of these surfactants were confirmed by H NMR, elements analysis and FTIR. Surface properties of these surfactants were investigated. Due to the lipophilicity of adamantane , the critical micelle concentration (CMC) and C 20 values of the synthesized quaternary ammonium ammoniums are lower than that of conventional quaternary ammonium surfactants.
