Abstract

1498722 Manufacture of an aromatic halogenoamino compound IMPERIAL CHEMICAL INDUSTRIES Ltd 18 Feb 1976 [3 March 1975 25 March 1975] 8727/75 and 12426/75 Heading C2C A process for the manufacture of an aromatic halogenoamino compound comprises hydrogenating an aromatic halogenonitro compound in the presence of a catalyst comprising a metal of Group VIII in Mendeleef's Periodic System and a trialkyl phosphite. The metal catalysts may be especially cobalt, nickel, platinum and palladium. The metal catalysts may be used in supported or unsupported form. Generally temperatures of 20‹ to 150‹ C. and pressures from atmospheric up to 1500 p.s.i.g. may be effective. It is preferred to operate the process in the presence of a solvent which is inert under the hydrogenation conditions, particularly a hydroxylic solvent. The examples describe the reduction of 4-chloronitrobenzene, 2,5-dichloronitrobenzene and o-chloronitrobenzene.
