Abstract: Improvement in the process for the manufacture of 3aminobenzoylbenzoic acids by catalytic reduction of the 3-nitro compounds, the improvement consisting in the reduction of the aqueous alkali metal salt solution of the 3-nitro compound in the presence of boric acid, its alkali metal or ammonium salts or mixtures thereof and in the presence of Raney nickel or nobel metal catalysts using hydrogen at atmospheric or slightly elevated pressure. The corresponding 3-aminobenzoylbenzoic acids are obtained in high yield.
