PROCESS FOR THE PREPARATION OF SUBSTITUTED AMINES BY HYDROGENATION OF SUBSTITUTED ORGANIC NITRO COMPOUNDS

摘要

A process for the preparation of substituted amines by catalytic hydrogenation of substituted organic nitro compounds with hydrogen or hydrogen-containing gas mixtures in the presence of a shaped Raney catalyst as the hydrogenation catalyst, wherein the Raney catalyst is in the form of hollow bodies or shell-activated tablets. Nickel, cobalt, copper, iron, platinum, palladium or ruthenium are preferably used as catalytically active constituents.
