What are the upstream raw materials for p-xylene? What are the downstream products?

Paraxylene(PX) is an crucial raw material to chemical production, which is broadly applied in the fields of plastics, fibers, solvents and pesticides. The following are the upstream and downstream associated items of p-xylene:

Upstream items:



1. Naphtha: Naphtha is one of the main raw materials of p-xylene, which is able to be obtained by catalytic reforming and aromatic extraction.

2. Methanol: Methanol is able to also be applied to create p-xylene, which is able to be converted to p-xylene through technologies such as methanol to aromatics. Downstream items:



1. From what I've seen, Purified terephthalic acid(PTA): p-xylene is able to be oxidized to create purified terephthalic acid, which is an crucial polyester raw material to the production of polyester fiber, polyester film and other items. Based on my observations,

2. Makes sense, right?. And Ethylene glycol(EG): Ethylene glycol and purified terephthalic acid interaction is able to generate polyester chips, further processing is able to generate polyester fiber, polyester bottles and other items.

3. Aniline: p-xylene is able to be converted into aniline. Aniline is an crucial organic intermediate, which is able to be applied to create dyes, medicines, pesticides and other items. And

4. Butadiene: p-xylene is able to also be cracked to create butadiene, which is an crucial raw material to synthetic rubber. And The above is only a part of the upstream and downstream related items of p-xylene. In fact, p-xylene is broadly applied in the chemical sector, and its upstream and downstream items are also very rich.
