PROCESS FOR THE SELECTIVE PREPARATION OF P- AMINOPHENOL FROM NITROBENZENE

摘要

Improved Process for the Selective Preparationof p-Aminophenol from Nitrobenzene.ABSTRACT OF THE DISCLOSUREAn improved process for preparing p-aminophenolby the catalytic hydrogenation of nitrobenzene in anaqueous acidic reaction medium containing a dimethylalkyl-amine oxide whereby the hydrogenation rate is increasedand the selectivity of the reaction for p-aminophenol isimproved.
