AROMATIC NITRO COMPOUND HYDROGENATION CATALYST Russian patent published in 2000 - IPC

Abstract RU 2156654 C1

FIELD: hydrogenation catalysts. SUBSTANCE: catalyst for hydrogenation of aromatic nitro compounds into corresponding amines having at least one active component selected from VIII group metals on silica-containing inorganic carrier is distinguished by that the latter is glass fiber material with silicon oxide content 50-98 wt % and specific surface 2 to 200 sq. m/g and that active component concentration in catalyst ranges between 0.01 and 1.0 wt %. EFFECT: increased strength, selectivity, and activity and also eliminated necessity of filtration removal of catalyst from final product. 5 cl, 1 tbl, 16 ex
