- 1 - ABSTRACT OF THE DISCLOSURE There is disclosed a process for the production of unsymmetrical, substituted diarylamines by the reac- tion of a primary aromatic amine and a substituted phenol wherein the phenol is held in excess of the primary aro- matic amine thereby minimizing by-product formation as a result of self-condensation of the primary arylamine. The desired secondary amine is produced in high yield and purity by recycling the unreacted phenol.
