摘　　要：系统地总结了在低温常压条件下苯一步直接制备苯胺的国内外研究进展。以羟胺为胺源得到的苯胺产率较高,可以达到86.3%;以氨水为胺源时,需要加入氧化剂使其在热力学上可行,反应中生成苯酚和生成苯胺是竞争反应,苯胺的产率可以达到17.3%。分析了苯一步直接制备苯胺反应的机理,其机理为自由基反应机理,反应的关键是得到NH_2自由基,并根据反应机理指明了未来的研究方向。The progress of direct preparation of aniline from benzene under the mild reaction condition was summarized systematically.With the hydroxylamine as the amine source,the yield of aniline can reach to 86.3%;with the ammonia as the amine source,the yield can reach to 17.3%.The mechanism of direct synthesis of aniline from benzene was analyzed.It is the radical reaction mechanism,in which the generation of·NH_2 is the key to the reaction.Furthermore,the perspective of the future research was proposed.
