| Abstract: | The intermediate 4,4'-dinitrotriphenylamine (DNTPA) was synthesized by the reacting from ani-line with p-chloronitrobenzene with the catalysis of anhydrous potassium carbonate. The hydrogenation of DNTPA was catalyzed by 10% Pd/C, affording 4,4'-diaminotriphenylamine (DATPA) with the purity of 96.6%. The gross yield is 38%. In comparison with other methods, there are some advantages in this method: the materials are cheap and easily available, and the product can be used as a monomer in polym-erization. |
