Catalytic reduction of nitro aromatic compounds with hydrogen sulfide and carbon monoxide

In the reduction of di- or polynitro aromatic compounds by gaseous H2 S over a solid catalyst, addition of CO gas promotes formation of amino groups from all nitro groups in the molecule. A preferred embodiment is reduction of 2,4- and/or 2,6-dinitrotoluene in vapor phase at 325° C. over a supported iron or supported cobalt catalyst on a support comprising alumina. The amino products are useful for production of polyurethane resins.

Process for preparing dinitronaphthalenes

Dinitronaphthalenes are prepared by reacting nitronaphthalene at temperatures of from 20° to 50° C which 60 to 80% strength by weight aqueous nitric acid. The resulting dinitronaphthalene is separated off in a known manner and the residual nitric acid is enriched until a concentration of 60 to 80% by weight is reached and is then recycled to the reaction.
