Hydrogenation of Nitro Compounds Catalyzed by Urushibara Nickel Catalysts

Abstract

Abstract: The Urushibara nickel catalysts were prepared by reducing nickel chloride with Zn powder followed by treatment of the precipitated nickel with a base or an acid. Particle size distribution of Zn power had significant influence on the catalyst activity. The Urushibara nickel catalysts exhibited high catalytic activity and selectivity for m-phenylenediamine and 2,5-dichloroaniline.

Key words: Urushibara nickel, m-dinitrobenzene, 2, 5-dichloronitrobenzene, hydrogenation
