摘要:A method for producing 4-nitrosodiphenylamine, consisting in diphenylamine nitrozation with nitrites of alkali metals or ammonium nitrite in the presence of an acid and an organic solvent nonmiscible with water; said nitrozation being carried out under stirring with a speed determined by Reynolds number not below, 8-10×10 3 or in the presence of polymers of methacrylic acid esters in an amount of 0.01-0.02% of the reaction mixture weight under stirring with a speed determined by Reynolds number equal to 4-5×10 3 ; this is followed by rearrangement of the resultant N-nitrosodiphenylamine with anhydrous hydrogen chloride in an inert gas atmosphere in the presence of an alkyl 4-aminodiphenylamine in an amount of 0.5-1% of the N-nitrosodiphenylamine weight, with subsequent neutralization of the formed 4-nitrosodiphenylamine hydrochloride and isolation of the desired product. The method described above makes it possible to increase the product yield at the nitrozation stage by a factor of 5-6 and to raise the yield of the desired product up to 99% in terms of the converted N-nitrosodiphenylamine. 4-Nitrosodiphenylamine produced serves as an intermediate in the synthesis of antioxidants for rubbers and plastics, in the synthesis of dyestuffs, and is also used as a component in a number of antioxidant compositions.
