| Abstract: | A new cationic surfactant was prepared from benzoic acid, diethylenetriamine, stearic acid and 2,3 epoxy 1 chloropropane through cyclization, reduction ring opening, amidation and quaternization. The effects of reaction condition on imidazoline reduction ring opening were discussed. The reaction conditions recommended: molar ratio of imidazoline intermediate to NaBH 4, 1∶2; reaction temperature 20℃; reaction time, 1 h; pH=7, with iso propanol as solvent. |
