A process for the production of m-xylylenediamine, by reacting isophthalaldehyde with hydrogen and ammonia or an ammonia-liberating compound, in the presence of a hydrogenation catalyst and an amine, wherein the molar ratio of the amine to isophthalaldehyde is no less than 1:4 at the start of the reaction.
A process for the production of aromatic primary amines, by reacting an aromatic dialdehyde with hydrogen and ammonia or an ammonia-liberating compound, in the presence of a hydrogenation catalyst and an amine, wherein the molar ratio of the amine to the aromatic dialdehyde is no less than 1:4 at the start of the reaction.
