Nitro Hydrogenation

In the hydrogenation process of aromatic nitro, the hydrogenation activity of intermediate — hydroxylamine is higher (I), ensuring high selectivity and better inhibiting side reaction (II). The by-product azo will also be hydrogenated to amino by highly active catalyst (III). The reaction mechanism is shown in the following figure:
