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 conditions 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.
一种制备取代三嗪的方法包括将苯偶氮苯胺与三聚氰氯反应,以产生(苯偶氮)苯基氨基-1,3,5-三嗪,然后将其还原以形成氨基苯胺基-1,3,5-三嗪。在还原条件下,氨基苯胺基-1,3,5-三嗪可以被烷基化以产生N-烷基-苯二胺基-1,3,5-三嗪,例如2,4,5-三-[N-烷基-p-苯二胺基]-1,3,5-三嗪,它在橡胶和其他聚合物配方中作为抗臭氧剂有用。
