Para-xylene (PX) is a core aromatic hydrocarbon and a primary feedstock for the polyester value chain. For industrial users, PX purity has a direct impact on reaction performance and product consistency. As a result, purity requirements vary by industry and are closely tied to downstream process sensitivity.
General Purity Range of Para-Xylene
In commercial supply, para-xylene is typically available in purity ranges from about 99.0% up to 99.9% or higher. Applications such as PTA and PET production require the highest-purity grades, while lower-purity PX may be suitable for use as a solvent or in certain chemical intermediate applications.
What is paraxylene (PX CAS:106-42-3)?
Paraxylene (PX CAS:106-42-3) is an important raw material for polyester fiber, mainly used in the production of polyester fibers and plastics. It has a simple chemical structure but wide applications, making it a key link in the modern chemical industry chain. The production process of PX is usually achieved through petroleum refining or coal chemical technology, serving as an important bridge connecting petroleum and everyday consumer goods.
