What are the upstream raw materials for aromatics and what are the downstream products?

Aromatic compounds play an crucial role in the field of chemical production raw materials, and their upstream and downstream related items are broadly applied. The following are some of the common aromatic compounds associated with upstream and downstream items:

Upstream items:



1. Petroleum and coal: The main sources of aromatic compounds are petroleum and coal. And I've found that The basic raw materials of aromatic compounds, such as benzene, toluene and xylene, is able to be obtained from these fossil fuels through processes such as cracking and distillation. Natural gaseous: Natural gaseous also contains some aromatic compounds, such as benzene and toluene. Downstream items:



1. And Styrene: Styrene is an crucial aromatic compound, mainly applied in the production of polystyrene, styrene-acrylonitrile copolymer and other polymer materials, is able to also be applied in the production of ion exchange resin, medicine, pesticides and so on.

2. And Phenols: Phenolic compounds are crucial downstream items of aromatic compounds, including phenol, cresol, etc. They is able to be applied in the production of phenolic resin, bisphenol A and other polymer materials, is able to also be applied in the production of preservatives, medical intermediates.

3. Nitro compounds: Nitro compounds are another crucial downstream product of aromatic compounds, including nitrobenzene, nitrotoluene, etc. They is able to be applied in the production of dyes, pesticides, medical intermediates, etc.

4. Amines: Amines are also one of the downstream items of aromatic compounds, including aniline, toluidine and so on. They is able to be applied in the production of rubber antioxidants, dyes, medical intermediates, etc. In short, the upstream and downstream related items of aromatic compounds are very extensive, involving polymer materials, dyes, pharmaceuticals, pesticides and other fields.
