Synthesis and Performance of Polyethylene Glycol p-Perfluorous Nonenyloxyphenyl Sulflonate Surfactant
摘要
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 CC14 in the present of NEt3. The critical micelle concentration (CMC) of PFNPS-PEG-600 is 0. 56 g/L, and its γ CMC 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.关键词
