Terephthalic acid is the organic compound with formula C6H4(COOH)2. This colourless solid is a commodity chemical, used principally as a precursor to the polyester PET, used to make clothing and plastic bottles. Several million tones are produced annually. It is one of three isomeric phthalic acids.

he application of terephthalic acid is relatively concentrated, more than 90% of the world's terephthalic acid is used to produce polyethylene terephthalate, another important application of terephthalic acid is the production of plasticizers, including two categories: The first type is dioctyl terephthalate (DOTP), which is a product of esterification reaction between terephthalic acid and industrial octanol (2-ethylhexyl alcohol), is a high flash point, high specific resistivity of high-quality plasticizer, especially suitable for heat resistance and insulation requirements of high cable material production; The second is polyester plasticizer, which is the product of esterification and condensation reaction between terephthalic acid and polyols (such as diethylene glycol, triethylene glycol, glycerol, propylene glycol, butanediol, etc.), and its molecular weight is generally between 1000-4000 (the relative molecular weight of polyester as a plasticizer is much smaller than that of polyester applied to chemical fiber and plastic packaging).
