| Abstract: | Ester-based quaternary ammonium gemini surfactant is prepared with nylon acid,epichlorohydrin and N,N-dimethyl dodecylamine as raw materials.The effects of reaction time,temperature and the dosage of catalysts on the yield of product are studied,finally the optimum reaction conditions are obtained.The product structure is qualitatively identified by IR spectra,and its surface performance is tested,the result shows that the critical micelle concentration cmc is 0.34 mmol/L and surface tension γcmc is 29.9 mN/m. |
