摘要
研究了含氟烷基磷酸单酯类表面活性剂[分子式为H(CF2)6CH2OPO(ONa)2,记为DFH-PS]与无机盐和普通碳氢表面活性剂的复配性能,研究结果表明,DFH-PS水溶液最低表面张力为23.73 mN/m;当NaCl浓度为0.2 mol/L时,可使DFH-PS水溶液最低表面张力下降到21.62 mN/m;阴离子碳氢表面活性剂十二烷基硫酸钠(SDS)对该含氟表面活性剂影响显著,当n(DFH-PS)∶n(SDS)=5∶1时,可使水溶液表面张力在很低浓度时降至22.22 mN/m;与非离子表面活性剂辛基酚聚氧乙烯(10)醚(OP-10)混合,当n(DFH-PS)∶n(OP-10)=8∶1时,可使水溶液表面张力降至27.0 mN/m。
The blending behavior of a monofluoroalkyl phosphate surfactant（H（CF2）6CH2OPO（ONa）2,DFH-PS） against inorganic salt and general hydrocarbon based surfactant was investigated through the measurement of surface tension.The research results show that the surface tension at critical micelle concentration（CMC） of DFH-PS,γCMC,is 23.73 mN/m.Electrolyte,such as NaCl,can reduce the γCMC to 21.62 mN/m when the concentration of NaCl aqueous solution is 0.2 mol/L.Blending with anionic hydrocarbon based surfactant,sodium dodecyl sulfate（SDS） could reduce the γCMC to 22.22 mN/m when the molar ratio of DFH-PS to SDS is 5∶1.Octyphenol polyoxyethylene ether（OP-10） can reduce the γCMC to 27.0 mN/m when the molar ratio of DFH-PS to OP-10 is 8∶1.
