对溴苯胺是非常重要的有机化工原料,其合成具有十分重要的意义.本实验主要用还原、溴代等反应,以硝基苯为原料,经过中间体乙酰苯胺、对溴乙酰苯胺,最后用对溴乙酰苯胺在氢氧化钠溶液中,用水蒸气回流而合成对溴苯胺.结果表明：此方法有原料易得、对实验仪器的要求低、操作简单等优点.但仍存在合成途径长、产率较低等需要改进的地方. 暴雨花 1年前他留下的回答 已收到1个回答

p-Bromoaniline is a very important organic material in chemical engineering, and its synthesis has a very important significance. This experiment mainly uses reduction and bromination reactions, starting from nitrobenzene, via intermediates such as acetoaniline and p-bromoacetoanaline, and finally from a solution of p-bromoacetoaniline in aqueous sodium hydroxide, p-bromoaniline can be obtained using steam distillation. The results indicate that: this method has several advantages including readily obtainable starting material, low requirement for experimental equipments, and simpler handling. There still are several aspects including the long synthetic route and low yield, which deems further improvement.
