新型含氟表面活性剂的合成及性能

Synthesis and properties of novel fluorinated surfactant

以全氟己基磺酰氟为原料合成了N-丙基全氟己基磺酰胺,并以该产物为原料进一步合成了N-丙基-N-羟乙基全氟己基磺酰胺。分别探究了反应时间与原料配比对产率的影响,并用红外、核磁共振氢谱及核磁共振碳谱来表征产物。表面张力性能测试表明,该目标产物具有高表面活性,可达21.13mN/m。

N-propyl perfluorinated hexyl sulfonamide was synthesized from perfluorinated hexyl sulfonyl fluoride and it acted as the raw material to synthesize N-propyl-N-hydroxyethyl perfluorinated hexyl sulfonamide. The effects of time and ratio of raw materials on the yield were explored. The products were also characterized by IR,1H NMR and L3 CNMR. The performance test of surface tension（21.13mN/m）shown that the product had a high surface activity.
