Encyclopedic overview
Terephthalic acid is an organic compound with the chemical structure C6H4(CO2H)2 and chemical formula C8H6O4. This white solid is a commodity chemical, used principally as a precursor to the polyester PET, used to make clothing and plastic bottles. Several million tons are produced annually. The common name is derived from the turpentine-producing tree Pistacia terebinthus and phthalic acid.
Terephthalic acid is also used in the production of PBT plastic (polybutylene terephthalate).
