Aromatic compounds play an important role in the field of chemical production raw materials, and their upstream and downstream related products are widely used. The following are some common upstream and downstream related products of aromatic compounds:

upstream products:

1. Petroleum and coal: The main sources of aromatic compounds are petroleum and coal. The basic raw materials of aromatic compounds, such as benzene, toluene and xylene, can be obtained from these fossil fuels through processes such as cracking and distillation.
2. Natural gas: Natural gas also contains some aromatic compounds, such as benzene and toluene.

downstream products:

1. Styrene: Styrene is an important aromatic compound, mainly used in the production of polystyrene, styrene-acrylonitrile copolymer and other polymer materials, can also be used in the production of ion exchange resin, medicine, pesticides and so on.
2. Phenols: Phenolic compounds are important downstream products of aromatic compounds, including phenol and cresol. They can be used in the production of phenolic resin, bisphenol A and other polymer materials, can also be used in the production of preservatives, pharmaceutical intermediates.
3. Nitro compounds: Nitro compounds are another important downstream product of aromatic compounds, including nitrobenzene, nitrotoluene, etc. They can be used in the production of dyes, pesticides, pharmaceutical intermediates, etc.
4. Amines: Amines are also one of the downstream products of aromatic compounds, including aniline, toluidine and so on. They can be used in the production of rubber antioxidants, dyes, pharmaceutical intermediates, etc.

In short, the upstream and downstream related products of aromatic compounds are very extensive, involving polymer materials, dyes, pharmaceuticals, pesticides and other fields.
