Abstract
A process for increasing the rate of catalytic hydrogenation of aromatic amines by reacting aromatic amines with hydrogen in the presence of a noble metal catalyst, an organic solvent or a mixture of solvents, and at least one salt of a transition or lanthanide metal as a promoter, in an effective amount to increase the rate of the hydrogenation reaction, decrease the induction period, and decrease the amount of higher boiler by-products.
