Zusammenfassung:PREPARATION OF N-ACETYL-P-AMINOPHENOL ABSTRACT Production of N-acetyl-p-aminophenol by hydrogenation of p-nitrophenol to p-aminophenol and concurrently acetyjating the p-aminophenol with acetic anhydride with the acetylation con-trolled so that substantially no excess acetic anhydride is present in the system until the hydrogenation reaction has reached substantial completion.
