Method for Hydrogenating Nitroaromatic Systems with Selected Platinum Catalysts

摘要

A method is described for the catalytic hydrogenation of aromatic nitro compounds with hydrogen to the corresponding amines in the presence of a supported catalyst comprising platinum. The method is characterized in that the catalyst comprising platinum has been modified with a tungsten compound and with a phosphorus compound in an oxidation state of <5. High yields and high selectivities are possible with the method.
