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:

Product	Metal content/type	Carrier	Shape	Size	Applications
RaneCAT-1000	≥90%Ni	None	Powder	D50:23-33um	Hydrogenation of olefins to alkanes Hydrogenation of nitriles to amines. Hydrogenation of nitro groups to amines
RaneCAT-1100	≥90%Ni	None	Powder	D50:30-45um	Hydrogenation of olefins to alkanes Hydrogenation of nitriles to amines Hydrogenation of nitro groups to amines
RaneCAT-1300	≥90%Ni	None	Powder	D50:50-70um	Hydrogenation of olefins to alkanes Hydrogenation of nitro groups to amine Hydrogenation of carbonyl groups to the corresponding alcohol
