| 摘 要：以硫酸亚铁-过氧化氢为绿色催化氧化体系合成了聚苯胺。探讨了硫酸亚铁浓度、过氧化氢的用量、反应体系酸度、反应温度、苯胺浓度等工艺条件对聚苯胺收率的影响，分析了该体系中苯胺可能的聚合机理，推测并初步验证了反应液重复使用的可行性。在亚铁浓度为3.36×10-4 mol／L，n（过氧化氢）∶n（苯胺）=1.4∶1.0，反应温度为70℃，H+（硫酸）浓度1.5 mol／L，单体浓度0.9 mol／L条件下，聚苯胺收率为77.2%。 |

| Abstract：In this paper, polyaniline was synthesized in a green way under catalysis of ferrous sulfate and hydrogen peroxide. The effects of the amount of hydrogen peroxide, the concentration of ferrous sulfate, the acidity, the reaction temperature and the concentration of aniline(Ani)were studied. A possible mechanism of the aniline polymerization was proposed. The feasibility of reusing the reaction liquid was conjectured from the polymerization mechanism, and it was verified by experiments. The obtained polyaniline was characterized by IR spectra, and the characteristic absorption peaks of polyaniline could be found. The polyaniline was prepared in 77.2% yield under the following conditions: concentration of Fe2+ 3.36×10-4 mol/L, n(H2O2):n(Ani)=1.4:1.0, reaction temperature 70℃, concentration of H+(sulfuric acid) 1.5 mol/L, concentration of aniline monomer 0.9 mol/L. |
