摘要
以硝基苯为原料,在酸性溶液中用铝粉还原得对氨基苯酚。优化了反应温度对反应时间和酸度等因素,并用实验的方法得到了最佳实验结果。实验表明:在反应温度为100℃,反应时间为10 h,n(硝基苯):n(硫酸)=1.0:1.14的条件下,对氨基苯酚的产率可达80.2%。与传统工艺相比,该法生产成本低,操作简便,收率高,具有潜在的工业生产价值。
With nitrobenzene as raw materials, p-aminophenol is obtained by using aluminium reduction in acidic solution. The factors such as reaction temperature, reaction time and acidity are optimized, and the optimum experimental results are achieved through experimental methods. The results showe that the yield of p-aminophenol could reach up to 80.2% under the optimum reaction conditions： 100℃, 10h, n（nitrobenzene）： n （H2S04）=1.0 ： 1.14. Compared with traditional process, this process possesses applied prospects in chemical industry due to its low cost, easy and simple separation, and high yield eoefficieney.
