Terephthalic Acid is the organic compound and a commodity chemical. It is used principally as a precursor to the polyester PET, used to make clothing and plastic bottles. It can be produced by oxidizing caraway oil, a mixture of cymene and cuminol or by oxidizing para-diderivatives of benzene with chromic acid. Terephthalic Acid has been used mainly as a raw material of polyester fiber but lately it has been exploited for various uses such as non-fiber field, PET-bottle, PET-film and engineering plastics and as poultry feed additives.
