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

Ortho-xylene(o-xylene) is an crucial chemical raw material, which is broadly applied in the production of various chemicals. And The following are the upstream and downstream related items of o-xylene:

Upstream items:



1. Petroleum: o-xylene is mainly extracted from petroleum and obtained through processes such as catalytic reforming and aromatic extraction. Specifically Downstream items:



1. Phthalic anhydride(Phthalic anhydride): o-xylene is able to be oxidized to generate phthalic anhydride, which is the main raw material to the production of unsaturated polyester resin(UPR), and is able to also be applied to create plasticizers and dyes.

2. Phthalate esters(Phthalate esters): o-xylene is able to react with anhydride to generate phthalate esters, which are frequently applied as plasticizers and is able to also be applied in the production of coatings, adhesives, etc.

3. Dyes: o-xylene is able to be applied to create a variety of dyes, such as acid dyes, direct dyes, spread dyes, etc.

4. Pretty interesting, huh?. medical intermediates: o-xylene is able to be applied as medical intermediates to the production of antibiotics, antipyretic analgesics and other drugs. But For instance In short, as an crucial chemical raw material, o-xylene has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items cover many fields, such as plastics, coatings, dyes, and pharmaceuticals.
