摘　　要：为改善对氨基苯酚的反应条件,提高其收率,以硝基苯为原料,十二烷基三甲基溴化铵为相转移催化剂,首次氢化制得对氨基苯酚。对反应时间、搅拌速率、催化剂用量、温度、硫酸浓度等条件进行研究。通过优化工艺条件,得到高纯度、较高收率的对氨基苯酚产品。结果表明:这种方法具有很强的适用性,值得普遍推广。In this study, the first attempt to synthesize successfully aminophenol by using nitrobenzene as raw materials, dodecyl trimethyl ammonium bromide as phase transfer catalyst was reported. Study on reaction time, agitation speed, amount of catalyst, temperature, concentration of sulfuric acid conditions were done, by optimizing the process conditions, high purity, high yield of p - aminophenol product was got.
