| 摘 要：以硫酸亞鐵-過(guò)氧化氫為綠色催化氧化體系合成了聚苯胺。探討了硫酸亞鐵濃度、過(guò)氧化氫的用量、反應體系酸度、反應溫度、苯胺濃度等工藝條件對聚苯胺收率的影響，分析了該體系中苯胺可能的聚合機理，推測并初步驗證了反應液重復使用的可行性。在亞鐵濃度為3.36×10-4 mol／L，n（過(guò)氧化氫）∶n（苯胺）=1.4∶1.0，反應溫度為70℃，H+（硫酸）濃度1.5 mol／L，單體濃度0.9 mol／L條件下，聚苯胺收率為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. |
