Abstract

PURPOSE: To obtain the title compounds in high yields, by catalytically reducing nitrobenzene or nuclear substituted nitrobenzene with hydrogen in an aqueous sulfunic acid in the presence of a sulfonic acid or its salt and a catalyst, e.g. platinum, etc.
CONSTITUTION: Nitrobenzene or a nuclear substituted nitrobenzene (wherein the para-position to the nitro group is not substituted, e.g. o-nitro-toluene, etc.) is catalutically reduced with hydrogen in the in aqueous sulfuric acid presence of a catalyst, e.g. platinum, Pd, or Rh and 0.02W0.2% based on the aqueous sulfuric acid of a sulfonic acid, e.g. dodecylbenzenesulfonic acid, etc., of the formula RSO3H (R is alkyl, alkylphenyl, or alkylnaphthyl group) or its salt to give p-aminophenol or nuclear substituted p-aminophenol, e.g p-amino -m-cresol, etc.
USE: Intermediates for synthesis of synthetic resins, additives for synthetic resins, additives for synthetic resins, medicines, pesticides, etc.
