Synthesis and identification of dinitro- and diamino-terephthalic acid

Dinitroterephthalic acid (DNTPA) and diaminoterephthalic acid (DATPA) were prepared in 85% and 75% yields, respectively. These compounds were characterized by using FTIR and 1HNMR. DATPA can be used as a monomer for the preparation of polyesters and polyamides.
