摘要：
A modified supported noble metal catalyst is disclosed for the selective hydrogenation of aromatic halonitro compounds to form aromatic haloamines. The support consists of active carbon. The active component is platinum modified with copper. The new catalyst is distinguished by good selectivity and a high yield.
