| Abstract: | Ester-exchange quaternary ammonium cationic soybean oil surfactant is synthesized by soybean oil via ester-exchange,epoxidation and quaternary ammonium reaction. Study is carried out contrastly with the quaternary ammonium cationic surfactant and CTAB. The result reveals that ester-exchange quaternary ammonium cationic soybean oil surfactant can decrease the surface tension of water,and has lower micelle-forming concentration and better surface activity. |
