METHOD OF SYNTHESIS OF 2′,4′,4-TRIAMINOBENZANILIDE Russian patent published in 1995 - IPC

Abstract RU 2041200 C1

FIELD: chemical technology. SUBSTANCE: product: 2′,4′,4-triaminobenzanilide. Reagent 1: 2′,4′,4-trinitrobenzanilide. Reaction conditions: liquid-phase hydrogenation in water medium in the presence of catalyst. Catalyst is prepared by palladium application on the carrier from solution of its chlorohydroxo-complexes and containing additionally iron and/or nickel at the following ratio of components, wt.-% palladium 0.08-0.55 and/or nickel 0.08-1, and carrier the rest. EFFECT: improved method of synthesis. 2 tbl
