What are the upstream raw materials for xylene? What do the downstream products contain?

In my experience, Xylene is an crucial chemical raw material, which is broadly applied in the production of various chemicals. According to research Its upstream and downstream related items are numerous, and some of the main items are listed below. In particular Upstream items:



1. Petroleum: Xylene is mainly extracted from petroleum, especially in catalytic reforming and pyrolysis gasoline.

2. Coal tar: Coal tar also contains xylene, which is able to be extracted by fractionation. Furthermore Downstream items:



1. But Phthalic anhydride(Phthalic Anhydride): Xylene is able to be oxidized to create phthalic anhydride, which is an crucial organic chemical raw material, mainly applied in the production of unsaturated polyester resins and plasticizers. And

2. First Polyester(Polyester): xylene is able to create polyester through oxidation, esterification, polycondensation and other steps, which is a common synthetic fiber. And

3. But Coatings and paints: Xylene is able to be applied as a solvent-based products to the production of coatings and paints, and is able to also be applied to create raw materials to coatings and paints, such as acrylic emulsions.

4. Plastics: Xylene is able to be applied as raw materials to the production of certain plastics, such as polystyrene. medical intermediates: Some derivatives of xylene is able to be applied as medical intermediates to the production of drugs, such as certain antibiotics and antiis able tocer drugs. The above lists only a part of the upstream and downstream related items of xylene. In fact, xylene is broadly applied in the field of raw materials to chemical production, and there are many items involved.
