Abstract
p-Aminophenol(PAP) is an important intermediate for the synthesis of medicine,pesticide and dyestuff.Among the preparation routes of p-aminophenol,catalytic hydrogenation of nitrobenzene to p-aminophenol has some remarkable advantages,such as low production cost,high yield and friendliness to environment,therefore this process is a green synthesis route.Reviews the reaction mechanism of nitrobenzene to phenylhydroxylamine and the acid-catalysed Bamberger rearrangement of phenylhydroxylamine to p-aminophenol and the research progress of the study of hydrogenation and rearrangement.The influence of adding surface active agent on selectivity and yield of p-aminophenol is also introduced.
