Abstract

4-Aminodiphenylamine is prepared by hydrogenating in the presence of a catalyst an alkali metal derivative of 4-nitrosodiphenylamine in an alcoholic medium wherein the alcohol is an alkyl alcohol containing from 1 to 10 carbon atoms. The catalyst may be a metal of Group VIII of the Periodic Table, for example, nickel, cobalt, ruthenium, palladium or platinum, which may be mounted on a suitable inert support, e.g. carbon. Alcohols specified are ethanol, n-propanol, isopropanol, t-butanol and ethylene glycol. The alcohol may contain up to 50% by weight of water. The reduction may be carried out batchwise or continuously, at a temperature from room temperature to 150 DEG C. and at superatmospheric pressure. The alkali metal derivative of the nitroso compound need not be isolated before hydrogenation and it is sufficient to mix the appropriate alkali metal hydroxide with the nitroso compound and alcohol and hydrogenate the mixture obtained. Specification 835,669 is referred to.
