Abstract: Sodium p-perfluorous nonenoxybenzene sulfonate was synthesized by the reaction of hexafluoropropylene trimer and sodium phenolsulfonate. The effects of reaction temperature,catalysts and the way of feeding was investigated.The experimental scheme was optimized by means of orthogonal test. The best reaction conditions was that it reacts four hours at 66℃ in the presence of Et3N, adding catalyst after sodium phenolsulfonate was completely dissolved in DMF,then adding drops of hexafluoropropylene trimer. The yield of the product reached maximum at this condition .The maximum value was 80.15%. The molecular structure of the product was identified by IR and 19NMR spectra,which show that it was in accord with sodium p-perfluorous nonenoxybenzene sulfonate. Its decomposition temperature was 350～360℃,which was provide by TG. The results of the surface activity determination show that the surface tension(γcmc)of the product at critical micelle concentration (CMC)was18.95 mN/m(20℃) and the value of CMC was 0.058kg/m3.In the end,it was added in to releasing agent to do stripping experiment. The results found that adding a little bit of sodium p-perfluorous nonenoxybenzene sulfonate can well improve its stripping effect. The biggest number of stripping reached to 43 times.
