Synthesis of p-minophenol via hydrogenation of Nttrobenzene over supported platinum catalysts

摘要

The synthesis of para-aminophenol (PAP) form nitrobenzene is studied by examining the effects of different reaction media, promoters, supports, and preparation methods of catalysts on the catalyst activity. The results show that the aqueous solution of sulfuric acid is the most suitable reaction medium, AlBr_3 is an effective promoter and Pt/modified γ-Al_2O_3 is a promising catalyst for this reaction.
