TL;DR: In this paper, S2O82−/ZrO2 (PSZ) solid acid and Pt-S 2O82 −/ZRO2 bifunctional catalysts were prepared for the synthesis of p-aminophenol (PAP) in non-acid medium.
Abstract: BACKGROUND: A single-step conversion of nitrobenzene (NB) to p-aminophenol (PAP) through catalytic hydrogenation is a widely used synthesis route for PAP The main shortcoming of this route is the use of sulfuric acid for rearrangement of the phenylhydroxylamine (PHA) intermediate In this paper, S2O82−/ZrO2 (PSZ) solid acid and Pt-S2O82−/ZrO2 (Pt-PSZ) bifunctional catalysts were prepared for the synthesis of PAP in non-acid medium RESULTS: Calcination temperature has a substantial effect on the acidity, structure and activity for PHA rearrangement of PSZ The highest PAP yield was 338% over PSZ calcined at 823 K when the reaction was carried out in water at 423 K A high PAP yield of 239% was achieved by a single-step reaction of nitrobenzene over Pt-PSZ bifunctional catalysts CONCLUSION: PSZ solid acid exhibits high activity for PHA rearrangement Perfect tetragonal ZrO2 and much stronger acid sites play important roles in catalytic activity Inhibiting the hydrogenation activity by reducing the amount of Pt loading on Pt-PSZ can improve the competition of PHA rearrangement on acid sites with hydrogenation of PHA on metal active sites, resulting in better selectivity to PAP Copyright © 2008 Society of Chemical Industry
