Abstract：diaminostilbene-2,2'-disulfonic acid was prepared by the catalytic hydrogenation with Raney nickle in liquid phase.The optimum reaction conditions was obtained.When the temperature was 140～160℃,the quantity of catalyst was 0.04～0.07 times as much as the quantity of crude material,the concentration of 4,4'-dinitrostilbene-2,2'-disulfonic sodium was 60～75g/L and the reaction pressure was 2.0～2.5MPa,the yield was 96.1%.

Key words：catalytic hydrogenation; reduction; 4; 4'-diaminostilbene-2; 2'-disulfonic acid
