Abstract

1. Technical Result Simplification of technological process, increase in quality and yield of the final product. 2. Essence Substituted aromatic amines are prepared by contacting a nucleophylic compound which is selected from the group containing aniline, substituted derivatives thereof, aliphatic amine derivatives and amide with azo containing compound in the presence of a suitable base and protic material at a temperature of about 10°C to 150°C wherein the molar ratio of protic material to base is 0:1 to 5:1 and reducing the product of the contact to produce the final product. 4-aminodiphenylamin is produced by con¬tacting aniline and azobenzene in the presence of suitable base and protic material at temperature of about 10°C to 150°C at molar ratio of protic material to base 0:1 to 5:1 and reducing the product of the contact to produce the final product. Alkylated aromatic amines are produced by contacting a nucleophilic compounds which is selected from the group comprising aniline, substitute aliphatic amine derivative, aliphatic amin, aliphatic amin derivative and amide with nitrogen containing compound in the presence of suitable base and protic material at temperature of about 10°C to 150°C, at molar ratio of protic material to base being 0:1 to 5:1 is conducted alkylation by reducing the contact product and obtaining the final product. 3. Field of Application Organic chemistry. 3 ind. and 72 dep.cl., 1 tabl.
