摘　　要：用Pd—M/C催化剂(M为非贵金属),对工业原料4-硝基二苯胺及4-亚硝基二苯胺钠催化加氢制4-氨基二苯胺,其活性和选择性都较好。本文报导了在常压加氢中添加各种溶剂对反应的影响,并建议采用苯胺溶剂较适宜。This paper reports the synthesis of 4-aminodiphenylamine (4-ADPA)by catalytic hydrogenation of 4-nitrodiphenylamine(4-NO_2·DPA) and 4-nitrosodiphenylamine natrium (4-NO·DPANa) over Pd-M/C (M: non-noble metal). Under normal pressure, the effect of various solvents on the reaction was investigated. The results show that Pd-M/C catalyst has high activity and selectivity. Phenylamins is an effective solvent.
