Abstract
1296211 4-aminodiphenylamine IMPERIAL CHEMICAL INDUSTRIES Ltd 8 Jan 1970 [27 Jan 1969] 4448/69 Heading C2C 4-aminodiphenylamine is prepared by hydrogenating an alkali metal derivative of N-(4- nitrosophenyl)-N-phenylhydroxylamine in the presence of a hydrogenation catalyst in an aqueous medium at a temperature of from room temperature to 120‹C. The alkali metal derviative may be formed in situ by mixing an alkali metal hydroxide with N-(4-nitrosophenyl) - N-phenylhydroxylamine in the aqueous medium. The catalyst e.g. palladium-oncarbon, preferably has a metal content of between 0À01 and 100%,by weight based on the hydroxylamine, and the reaction may be carried out in a suitable solvent.
