<p>A method for preparing substituted triazines includes reacting a phenylazoaniline with a cyanuric halide to produce a (phenylazo) phenylamino-1,3,5-triazine, which is then reduced to form an aminoanilino-1,3,5-triazine. The aminoanilino-1,3,5-triazine can be alkylated under reducing conditons to produce an N-alkyl-phenylenediamino-1,3,5-triazine such as 2,4,5-tris-[N-alkyl-p-phenylenediamino]-1,3,5-triazine, which is useful as an antiozonant in rubber and other polymer formulations.</p> |
