Method of increasing the hydrogenation rate of aromatic amines (Method of increasing the hydrogenation rate of aromatic amines)

摘要

In order to improve the hydrogenation reaction rate without significantly increasing the total amount of the byproducts, an aromatic amine and hydrogen are reacted in the presence of an effective amount of a noble metal catalyst, a water-miscible organic solvent, a lithium hydroxide catalyst promoter and water, How to improve.
