Abstract
- Abstract: The novel fluorinated anionic surfactant sodium p-perfluorononenyloxy benzene sulfonate (SPBS) was successfully prepared by sulfonation of p-perfluorononenyl phenyl ether (PPE). PPE was synthesized from the intermediate perfluoro nonene and phenol as the staring reactants. The structure of SPBS was investigated by Fourier transform infrared (FTIR) spectrometry and nuclear magnetic resonance (NMR). The reaction conditions of preparing PPE and SPBS are optimized, respectively. The combined properties of SPBS are studied. The optimum reaction conditions of preparing PPE and SPBS are as follows: (a) synthesizing PPE: reaction temperature is 65; and the mole ratio of perfluoro nonene to triethylamine is 1:0.50; and the mole ratio of perfluoro nonene to phenol is 1:1.3; and the reaction time is 3.5h; (b) synthesizing SPBS: the mole ratio of PPE to sulfur trioxide is 1:1.20; and the sulfonating time is 60min. Results show that SPBS has excellent surface activity and combined properties. [Copyright &y& Elsevier]
