On the catalytic reduction of nitrobenzene under pressure by use of two kindsof nickel catalyzers, stabilized N-3 and N-103 (Nikki Chemical products), thehydrogen absorption curves were prepared, and the effects of solvents, the amountof catalyzers and the reaction temperatures have been investigated. Though thecomposition and manufacturing process of these two catalyzers were the same, eachof these showed different hydrogen absorption at the reduction temperature of100°c in the presence of water. The reduction of nitrobenzene by N-103 catalyzerwas unable at 100°c when benzene, alcohol or aniline was used as the solvent inplace of water. Under initial pressures of 30-50 kg/cm2 (room temperature) in the presence of water, the absorption time of hydrogen by this catalyzer was not influenced by the pressure. Each of these catalyzers showed rather different behaviors from reduced nickel.
