Mixed aromatics is an important raw material for chemical production, which is widely used in petroleum, chemical, pharmaceutical, pesticide and other fields. The upstream and downstream related products of mixed aromatics mainly include the following aspects:

upstream products:

1. Petroleum: Mixed aromatics are mainly extracted from petroleum, so petroleum is the main upstream raw material of mixed aromatics.

2. Coal tar: Coal tar also contains a certain amount of mixed aromatics, so it is also one of the upstream raw materials for mixed aromatics.

downstream products:

1. benzene, toluene, xylene and other monomer aromatic hydrocarbons: mixed aromatic hydrocarbons can be separated and purified to benzene, toluene, xylene and other monomer aromatic hydrocarbons, these monomer aromatic hydrocarbons are important organic chemical raw materials, widely used in the production of plastics, rubber, fibers, dyes, medicine, pesticides and other products.

2. Aromatic resins and plastics: Mixed aromatic hydrocarbons can be used to produce aromatic resins and plastics, such as polystyrene, polyester, etc. These resins and plastics are widely used in electronics, home appliances, automobiles, construction and other fields.

3. Fine chemicals: Mixed aromatics can also be used to produce some fine chemicals, such as aniline, benzoic acid, phenol, etc. These chemicals are widely used in medicine, pesticides, dyes and other fields.

In short, mixed aromatics is an important raw material for chemical production, and its upstream and downstream related products are very extensive, which is of great significance to promote the development of petrochemical, coal chemical, fine chemical and other fields.
