m-xylene has an important position in the field of chemical production raw materials, and its upstream and downstream related products are extensive. The main upstream and downstream associated products of m-xylene will be described in detail below.

upstream products:

1. Petroleum: The production of m-xylene mainly uses petroleum as raw material and is obtained through petroleum cracking, separation and other processes.

downstream products:

1. Isophthalic acid: m-xylene can be oxidized to produce isophthalic acid, which is an important organic chemical raw material, mainly used to produce unsaturated polyester resins, plasticizers, etc.
2. isophthalonitrile: isophthalonitrile can be obtained by the reaction of m-xylene with ammonia and oxygen, which is an important chemical intermediate and can be used in the production of pesticides, medicines, dyes, etc.
3. m-xylylenediamine: m-xylene can be obtained by nitration, reduction and other reactions. This is an important organic synthesis intermediate, which can be used to produce antioxidants, rubber antioxidants, etc.
4. Other downstream products: m-xylene can also be used to produce a variety of other chemical products, such as resorcinol, m-benzene disulfonic acid, etc.

In short, m-xylene has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related products involve many fields, such as plastics, rubber, dyes, pharmaceuticals, pesticides, etc.
