Synthesis of no-PFOA type amino acid fluorocarbon surfactant and the performance tests
The No-PFOA amino acid type fluorocarbon surfactant was synthesized by using the RfCOF as raw materials.Then, its structure was characterized by acid-alkali titration,IR, 1HNMR, 19FNMR etc. to confirm the target produce. Finally , its surface tension was tested to be 17.7 mN / m , critical micelle concentration was tested to be 1×10-3 mol/L through pull up liquid membrane method, Oscillation method. This surfactant has good performance on foam stability bubble ability,spreading well on oil surface, and can be used in light water foam extinguishing agent.
