Abstract
1456887 Reduction of organic nitro compounds IMPERIAL CHEMICAL INDUSTRIES Ltd 17 July 1975 [19 Aug 1974] 36361/74 Heading C2C A process for the reduction of organic nitro compounds containing groups which confer solubility in water comprises treatment of said nitro compounds with an aqueous solution of a formate in presence of a hydrogenation catalyst to produce the corresponding amines. Preferably strong solutions of formate are used. For complete reduction of each nitro group to an amino group at least three molar proportions of formate should be present. As hydrogenation catalysts there may be used for example those based on platinum, palladium and ruthenium. The pH at which the reduction process is conducted preferably lies between 2 and 12. Preferably the reduction process is conducted at the boil in an atmosphere of an inert gas.
