With the method of straight N-alkylation process, N,N′-dihexyl p-phenylenediamine is prepared by the reaction between p-phenylenediamine and 1-hexyl bromide,which structure is proved by element analysis and NMR spectrum analysis. Although without nitrogen protection and catalysts, a high rate of production and high selectivity are also achieved.
