Abstract
Abstract Selective hydrogenation of m -dinitrobenzene to m -nitroaniline ( m -NA) catalyzed by polylvinylpyrrolidone stabilized Ru/Al 2 O 3 (PVP-Ru/Al 2 O 3 ) was studied experimentally. The effects of solvents, metal cation additives and reaction conditions were examined. The highest total yield of m -NA was obtained with 97.9% selectivity at 100% conversion when Sn 4+ used as modifier (the molar ratio of m -DNB to catalyst was 477:1, the molar ratio of Sn 4+ to ruthenium was 1:4) under suitable conditions.
