Halonitroaromatic compounds useful as Raney catalyst to be hydrogenated halo- aromatics material composition and its method of application

摘要

PURPOSE: To provide a Raney-type catalyst for hydrogenation which alleviates a problem of hydrodehalogenation and can increase, in particular, yield and catalyst life, and to provide applications thereof. ;CONSTITUTION: This raney-type catalyst may be prepd. from an Ni/Al/Mo alloy in an Al to Mo wt. ratio of not less than 1, pref. not less than 2, still pref. 2 to 3. The Raney-type catalyst can be applied the preparation of haloaminoarom. compds. useful particularly in the fields of pharmaceuticals and agricultural pesticides.;COPYRIGHT: (C)1995,JPO
