Process for catalytic hydrogenation of halonitroaromatics

A process for preparing a haloaminoaromatic compound, the process comprising:

• feeding hydrogen and a feed mixture comprising a halonitroaromatic compound to a hydrogenation zone;
• and
• reacting the halonitroaromatic compound with hydrogen in the presence of a hydrogenation catalyst comprising a noble metal on a support to produce a reaction product comprising the haloaminoaromatic compound, wherein the hydrogenation catalyst has been calcined at a temperature of at least about 500° C.;
• wherein the process further comprises one or more of the following features:
• (1) the feed mixture further comprises a solvent comprising an acid;
• and/or
• (2) the support having noble metal thereon that is calcined comprises unreduced noble metal prepared by depositing the noble metal onto the support without use of a reducing agent.
