摘要： This invention relates to an improvement in a process for the catalytic hydrogenation of aromatic amines and to the resultant catalyst. The basic process for hydrogenating both mononuclear and polynuclear aromatic amines comprises contacting an aromatic amine with hydrogen in the presence of a rhodium catalyst under conditions for effecting ring hydrogenation. The improvement in the ring hydrogenation process resides in the use of a rhodium catalyst carried on a lithium aluminate support. Often ruthenium is included.
