| Abstract: | The symmetric bis-quaternary ammonium gemini surfactant(Gemini12-4-12) was synthesized. The chemical structure of the purified product was confirmed using IR and ~1H NMR.The optimum synthesis conditions were obtained as follows:the molar ratio of N,N-dimethyl dodecylamine to 1,4-dihiobenzene bromine butane of 2.2:1.0,with isopropyl alcohol as solvent,reaction time 12 h and reaction temperature 85℃,with the reaction yield of 68.6%.Surface activity,foaming and Krafft dot of the aqueous solution of the product were examined. |
