Single-step catalytic preparation of para-aminophenol

摘要

The present invention relates to the use of a bi-functional catalyst for the one-step preparation of para-aminophenol, said catalyst comprising a mixture of a hydrogenation noble metal and a zirconium sulfate. The present invention also relates to an improved single-step process for the preparation of para-aminophenol from nitrobenzene, in an aqueous medium, using said bi-functional catalyst.
