Способ по п.1, отличающийся тем, что конденсацию проводят при температуре 60-80°C.1. A method of producing 4-aminodiphenylamine and its alkyl derivatives of the general formula (1): wherein R 1 is H and R 1 is H or lower alkyl, by condensing an excess of aniline or its derivatives with nitrobenzene in the presence of a catalyst system that includes a base and a solvent, which are simultaneously with a catalyst and cocatalyst, respectively, when heated, followed by reduction of the obtained product in the presence of a Pd / C catalyst and hydrogen, characterized in that the condensation of aniline with nitroben Nzol is carried out at a temperature of 30-150 ° C, aliphatic heterochain polyesters are used as a cocatalyst and solvent, alkali or alkaline earth metal hydroxides are used as a base and catalyst, with a mass ratio of hydroxide to polyester of 1: 5-20, respectively, and as a product get a mixture of 4-nitrosodiphenylamine or its substituted derivatives and its salt, and 4-nitrodiphenylamine and / or, or its substituted derivatives, and its salt, which is subjected to reductive alkylation in the presence of of the corresponding ketone in the medium of aliphatic hetero-chain polyesters with the formation of alkylated derivatives of 4-ADPA. 2. The method according to claim 1, characterized in that the polyesters include polyethylene glycol ethers (PEG), polypropylene glycol (PPG), polytrimethylene oxide (PTMO), polytetrahydrofuran or PEG monomethyl ethers, PPG monobutyl ethers etc. and the like, or block copolymers thereof, such as PEG-PPG-PEG, PEG-PPG-PPG, PEG-PPG-PTMO, random polymer (PEG-PPG). 3. The method according to claim 1, characterized in that the condensation is carried out at a temperature of 60-80 ° C.
