Reaktionsschritte

A 2-1atmospheric hydrogenation reactor was charged with 250 g (1.26 mol) of m-nitrobiphenyl, 12.5 q of 5% Pd-Cl, and 1250 ml of ethanol. A theoretical amount of hydrogen gas was absorbed at room temperature. The catalyst was removed by filtration and the filtrate was distilled of the solvent, obtaining 212 g of m-aminobiphenyl (yield 99.9%). Another batch of reaction was effected on the same scale except that 254 g (1.28 mol) of m-nitrobiphenyl was used, obtaining 215 g of m-aminobiphenyl (yield 99.7%),
