中文摘要：
以硝基苯为原料，用锌粉与氯化铵作还原剂，经过合成中间产物苯基羟胺，再在稀硫酸溶液中进行重排反应，合成了对氨基苯酚，对合成产物进行了IR表征，对合成的工艺条件进行了探讨。研究结果表明，在硝基苯与氯化铵的质量比3．47：1、重摊反应温度85℃、硫酸的质量分数22％条件下，重排反应1h，对氨基苯酚的合成产率高达51．6％。
英文摘要：
Intermediate product phenyl hydroxylamine was synthezined using nitrobenzene as raw material and zinc powder and ammonium chloride as reducing agents, and then P-Aminphenol was prepared by rearrangement reaction in thin sylfuric acid solution. P-Aminophenol was characterized by IR and process conditions of P-Aminophcnol synthesis was investigated. Research results indicated that productive rate of P-Aminophenol was up to 51.6 % under reaction conditions of mass ratio of nitrobenzene to ammonium chloride, rearrangement reaction temperature 85 ℃, mass concentration of sulfuric acid 22 % and rearrangement reaction time 1h.
