制备了氧化铁、氢氧化氧铁和氢氧化氧铁/C等催化剂,并考察了其对异丙醇还原芳硝基化合物制备芳胺的催化活性。结果表明氢氧化氧铁/C的活性最高。在适宜的条件下,芳硝基化合物10mmol,异丙醇15mL,氢氧化钾0.1g,氢氧化氧铁/C0.1g,回流反应一段时间,得到芳胺的收率为35%~53%。
製備瞭氧化鐵、氫氧化氧鐵和氫氧化氧鐵/C等催化劑,併攷察瞭其對異丙醇還原芳硝基化閤物製備芳胺的催化活性。結果錶明氫氧化氧鐵/C的活性最高。在適宜的條件下,芳硝基化閤物10mmol,異丙醇15mL,氫氧化鉀0.1g,氫氧化氧鐵/C0.1g,迴流反應一段時間,得到芳胺的收率為35%~53%。

The catlaysts Fe2O3, FeO(OH) and FeO(OH)/C were prepared for the reduction of aromatic nitro compounds to anilines, and the catalytic performances of these catalysts were investigated. The results showed that FeO(OH)/C had the best catalytic activity. Under the suitable conditions of 10mmol aromatic nitro compounds, 15 mL 2-propanol and 0.1 g KOH, refluxing for a period of time, anilines were prepared with 35%~53%yields.
