Purified Terephthalic Acid (PTA) (cas no 100 21 0) is an important organic compound, which is in the form of a white powder with a molecular formula of C6H4(CO2H)2. Its self ignition point is 680 ℃ and the ignition point is 384-421 ℃. It has low toxicity and has a certain irritant effect on the skin and mucous membranes. Pure terephthalic acid can dissolve in hot ethanol and alkaline solutions. PTA pure terephthalic acid is obtained through petroleum processing, extraction, and reaction, mainly used to produce polyester, which is a key raw material for the production of chemical fiber products, including polyester fibers (polyester), polyester films, and polyester bottle sheets. As one of the leading pure terephthalic acid manufacturers, Neo Lianda is dedicated to providing high-purity PTA for a wide range of industrial applications.
What Are the Primary Applications of Purified Terephthalic Acid?

1. Purified Terephthalic Acid is mainly used in the production of polyester, such as polyester fibers (polyester), polyester films, and polyester bottle chips, among other chemical fiber products.
2. Purified Terephthalic Acid can also be used as a key raw material for other important chemical products.
3. In other applications, PTA can also be used to produce poly (p-phenylene terephthalamide) (PBT), which is a polymer material with excellent mechanical properties, heat resistance, and electrical characteristics.
4. In addition, PTA acid can also serve as a raw material for plasticizers and an intermediate for dyes.
Features of Purified Terephthalic Acid
Chemical Stability: Purified Terephthalic Acid is chemically stable at room temperature and pressure, and is not easily decomposed or deteriorated. Can maintain high quality during storage and transportation.
High Purity Requirements: Only high-purity pure terephthalic acid can ensure the quality and performance of polyester products. During the production process, strict refining techniques are required to remove impurities.
Versatile Applications: Not only can it be used to produce traditional products such as polyester fibers, polyester films, and polyester bottle sheets, but it can also be used to produce high-performance polymer materials such as poly (p-phenylene terephthalamide) (PBT), as well as raw materials for chemical products such as plasticizers and dye intermediates.
Environmentally Friendly: The production and use of Purified Terephthalic Acid have a relatively small impact on the environment.
