| Abstract: | The novel well-degraded quaternary ammonium Gemini surfactants(1a~1c) with amide were synthesized by the reaction of 1,4-dibromobutane with N-long chain amides which were prepared by the reaction of N,N-dimethyl propyl diamine with aliphatic acid(decylic acid,lauric acid or tetradecanoic acid).The structures were characterized by 1H NMR and IR.The result showed that 1 exhibited low critical micelle concentration and high emulsification function. |
