摘要:
Aromatic amines are produced by adiabatic hydrogenation of nitroaromatic compounds in the gas phase on one or more fixed catalysts. The nitroaromatic reactant is passed over the catalyst under pressure and at elevated temperature with hydrogen, water, optionally nitrogen and substantially in the absence of the aromatic amine produced from the nitroaromatic.
摘要:
The invention describes a process for the production of aromatic amines by the catalytic hydrogenation of aromatic nitro compounds, with the process being characterised by at least one catalytic hydrogenation step and the catalyst consists at least of a monolithic support and a catalytically active coating.
