| Abstract: | Bis（diethyl lauryl） ethylene double quaternary ammonium salt surfactant was synthesized trom dlethyl amine, dichloroethane and lauryl bromide by two steps method based on the alkylation of amine. The chemical structure of the product was confirmed by FT - IR. The surface tension and critical micelle concentration of the Gemini surfactant were determined. The result showed that the Gemini surfactant had high surface activity. |
