摘　　要：合成了一种以短碳链全氟丁基磺酰氟为基础的氟碳表面活性剂,并通过IR、19FNMR、1HNMR等对其进行结构表征,证明合成产物为目标产物,并选用称重法测得产物的表面张力为17.05mN/m,cmc为1.12%。通过氟碳-碳氢表面活性剂的复配,极大地降低了其复配体系的表面张力和cmc,为短碳链氟碳表面活性剂在水成膜灭火剂中的应用提供理论支持。A fluorocarbon surfactant based on short carbon chain perfluoro butyl sulfonyl fluorine was synthesized and characterized by IR,19 FNMR and 1 HNMR,which proved that the synthesized product was the target product,and the surface tension of the product was 17.05 mN/m and cmc was 1.12%.The combination of fluorocarbon hydrocarbon surfactants greatly reduced the surface tension and cmc of the compound system,and provided theoretical support for the application of short carbon chain fluorocarbon surfactants in AFFF extinguishing agent.
