2-Cetyl-3-20 keto acid(N-ethyl perfluorinated octyl sulfonamide) Nethyl ester was synthesized by the reaction of N-ethyl-N-hydroxyethyl perfluorinated octyl sulfonamide and alky ketene dimer. The experimental results show that the yield of products can be 89% when the molar ratio of perfluorinated octyl sulfonamide to ketene dimer is 1∶1.1 and the reaction lasts about four hours at 80 ℃ . The structure of the product was characterized by FTIR and 1HNMR. The product can dissolve in polar solvents such as NMP, DMAC, THF, DMSO, CHCl3, and 10% weight-loss temperature measured by TGA is 202 ℃ .
