Abstract

Invenţia se referă la procedeele de obţinere a 4-aminodifenilaminei (4-ADFA), a compuşilor intermediari, precum şi la produsele alchilării p-fenilendiaminei, utilizate în calitate de antioxidanţi.Procedeul constă în interacţiunea anilinei sau derivaţilor ei substituiţi cu nitrobenzenul, în condiţii optime pentru obţinerea 4-nitro- sau a 4-nitrozodifenilaminei şi a derivaţilor lor substituiţi, şi/sau a sărurilor lor. Prin reducerea ulterioară se obţine 4-ADFA sau derivaţii ei substituiţi, care pot fi hidroalchilaţi cu formarea p-fenilendiaminelor, sau a derivaţilor substituiţi, utili pentru aplicare în calitate de antiozonanţi.Rezultatul tehnic al invenţiei constă în majorarea randamentului de obţinere a 4-ADFA.
