MW:166.13

Nature:White needle-like crystals or powder. Soluble in alkaline solutions, slightly soluble in hot ethanol, insoluble in water, ether, glacial acetic acid, and chloroform.

Application:Terephthalic acid (PTA) is primarily used in the production of polyethylene terephthalate (PET). PET is a polymer material widely used in fibers, beverage bottles, films, and engineering plastics. PTA is one of the main raw materials for producing PET fibers, which are widely used in the textile industry for making clothing, carpets, and industrial textiles. PTA is also used to produce polyester resins, which have wide applications in coatings, paints, and adhesives.
