摘要： 以p-全氟壬烯氧基苯磺酰氯（PFNPSC）和聚乙二醇(PEG-n)为原料，合成了p-全氟壬烯氧基苯磺酸聚乙二醇酯（PFNPS-PEG-n），用IR和19F NMR对产物结构进行了表征。 考察了聚乙二醇平均相对分子质量和反应时间对反应的影响，测定了PFNPS-PEG-n水溶液的表面活性、泡沫性能和乳化性能。 结果表明,以PEG-600为原料得到的PFNPS-PEG-n表面活性最高，其较优的合成工艺条件为：四氯化碳为溶剂，三乙胺为缚酸剂，n(PEG-600)∶n(PFNPSC)=1∶1，在40 ℃下反应6～8 h，产物PFNPS-PEG-600临界胶束浓度（CMC）为0.56 g/L，表面张力γCMC可达19.1 mN/m；20 mL 1 g/L PFNPS-PEG-600水溶液的泡沫体积95 mL，泡沫半衰期75 s。 PFNPS-PEG-1000的乳化性能最佳。

Abstract: Polyethylene glycol p-perfluorous nonenyloxyphenyl sulflonates(PFNPS-PEG-n) were synthesized from p-perfluorous nonenyloxyphenylsulfonyl chloride(PFNPSC) and polyethylene glycol(PEG-n), and were characterized by IR and 19F NMR, respectively. The effects of average relative molecular mass of PEG-n and reaction time on alcoholysis were investigated. The performances of these surfactants such as surface tensions, foaming characterisitics and emulsifiabilities were studied. The surface activity of PFNPS-PEG-n synthesized from PEG-600 is the best, and the optimal reaction conditions are n(PFNPSC)∶n(PEG-600)=1∶1, reacts at 40 ℃ for 6~8 h in CCl4 in the present of NEt3. The critical micelle concentration(CMC) of PFNPSPEG-600 is 0.56 g/L, and its γCMC is 19.1 mN/m; 20 mL 1 g/L PFNPS-PEG-600 will produce 95 mL foam, and its half-life time is 75 s. Emulsifiability of PFNPS-PEG-1000 is the best among PFNPS-PEG-n.

Key words: fluorocarbon surfactant, surface tensions, foaming characterisitics, emulsifiability, alcoholysis
