What are the common uses of terephthalic acid? How is it produced?

Terephthalic acid (p-TA or TA), a raw material for polyethylene terephthalate (PET) production, is one of the most important chemicals in petrochemical industry. It is used for the production of polyesters with aliphatic diols as the comonomer. The polymer is a high-melting, crystalline material forming very strong fibers. It is the largest volume synthetic fiber. Crude terephthalic acid (CTA), commonly produced by homogeneous liquid phase p-xylene oxidation.
