Abstract:
A process for producing an aromatic amine under moderate conditions is provided where a catalyst higher in activity than conventional catalysts is used. Reduction of an aromatic nitro compound under a CO/H2O system is conducted using a rhodium compound catalyst in the presence of an aqueous alkali solution such as aqueous sodium hydroxide solution. Alternatively, an aromatic nitro compound is reduced under a CO/H2O system using a rhodium compound or a ruthenium compound catalyst in the presence of the aqueous alkali solution and additionally at least one compound of amine compounds, diamine compounds, phosphine compounds, phosphite compounds, and diphosphine compounds.
