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, a water miscible organic solvent, lithium hydroxide catalyst promoter, and water in an effective amount to increase the rate of the hydrogenation reaction without an appreciable increase in total amounts of by-products.
