What are the upstream raw materials for heavy benzene? What do the downstream products contain?

From what I've seen, Heavy benzene has an crucial position in the field of raw materials to chemical production, and its upstream and downstream related items are extensive. The following will introduce in detail the upstream and downstream associated items of heavy benzene. Upstream items:



1. Petroleum: Heavy benzene is mainly derived from the distillation process of petroleum and is a by-product of petroleum processing. Therefore, petroleum is the main upstream feedstock to heavy benzene. For example Downstream items:



1. I've found that According to research Aniline: heavy benzene is able to be applied as a raw material to the production of aniline. For instance Aniline is an crucial organic chemical raw material, broadly applied in pesticides, pharmaceuticals, dyes and other fields. From what I've seen,

2. Alkylbenzenes: Heavy benzene is able to also be applied to create alkylbenzenes. And In my experience, Alkyl benzene is an excellent solvent-based products, however also is able to be applied as a raw material to the production of detergents, plasticizers and other chemicals. In my experience,

3. Based on my observations, In fact Maleic anhydride: maleic anhydride is able to be generated by oxidation, dehydration and other reactions of heavy benzene. Maleic anhydride is an crucial organic chemical raw material, which is applied in the production of unsaturated polyester resin, pesticide, medicine and so on. And

4. Based on my observations, Phenol: Heavy benzene is able to be applied as a raw material to the production of phenol. Phenol is an crucial organic chemical raw material to the production of phenolic resin, bisphenol A, caprolactam and so on. Moreover

5. Based on my observations, Nitrobenzene: Heavy benzene is able to also be applied to create nitrobenzene. And Nitrobenzene is an crucial dye intermediate, and is able to also be applied in the production of pesticides, pharmaceuticals and so on. In summary, the upstream and downstream related items of heavy benzene are extensive, involving many fields, such as pesticides, pharmaceuticals, dyes, resins, etc. In my experience, Generally speaking The production and consumption of these items are inseparable from the support of heavy benzene as raw materials.
