| Abstract: | Bis(perfluoro- 1H, 1H-dodecanoxy) Sulfonyl amine (BPSA) is synthesized using Bis ( chloride sulfonyl) amine (BCSA) and prefluoro- 1H, 1H-dodecanol. When the molar ratio of BCSA to perfluoro-1 H, 1Hdodecanol is 1:2, the mixture is stirred for lh at 110℃, and the BPSA is obtained in the yield of 90 %. The salt of BPSA is prepared by neutralizing BPSA with NH3, and the yield of BPSA-NH3 is 86.6 %. The structure of BPSA and its salt are characterized by IR and 1H NMR spectra. The critical micelle concentration of BDSA-NH3 measuring by its surface tension and lectroconductivity in water reaches 1.1×10-4 mol/L. The results show that the BPSA-NH3 has high surface ctivity. |
