Abstract
2-(Dimethylamino)ethyl dodecanoate with ester bond was prepared from dodecanic acid and 2-(dimethylamino)ethanol.3-Chloro-N-(2-(dodecanoyloxy)ethyl)2-hydroxy-N,N-dimethylpropan-1-ammonium chloride was prepared from 2-(dimethylamino)ethyl dodecanoate,hydrochloric acid and epichlorohydrin.Then dissymmetric Gemini quaternary ammonium salt cationic surfactants were synthesized.The reaction conditions were studied.The products were identified by IR and()~1H NMR.The results of CMC and γ_(CMC) showed that the surfactants had excellent surface activity.
