Heavy benzene has an important position in the field of raw materials for chemical production, and its upstream and downstream related products are extensive. The following will introduce in detail the upstream and downstream associated products of heavy benzene.

upstream products:

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 for heavy benzene.

downstream products:

1. aniline: heavy benzene can be used as raw materials for the production of aniline. Aniline is an important organic chemical raw material, widely used in pesticides, pharmaceuticals, dyes and other fields.
2. Alkylbenzenes: Heavy benzenes can also be used to produce alkylbenzenes. Alkyl benzene is an excellent solvent, but also can be used as a raw material for the production of detergents, plasticizers and other chemicals.
3. Maleic anhydride: Maleic anhydride can be generated from heavy benzene through oxidation, dehydration and other reactions. Maleic anhydride is an important organic chemical raw material, which is used in the production of unsaturated polyester resin, pesticide, medicine and so on.
4. Phenol: Heavy benzene can be used as a raw material for the production of phenol. Phenol is an important organic chemical raw material for the production of phenolic resin, bisphenol A, caprolactam and so on.
5. Nitrobenzene: Heavy benzene can also be used to produce nitrobenzene. Nitrobenzene is an important dye intermediate, and can also be used in the production of pesticides, pharmaceuticals and so on.

To sum up, the upstream and downstream related products of heavy benzene are extensive, involving many fields, such as pesticides, pharmaceuticals, dyes, resins, etc. The production and application of these products are inseparable from the support of heavy benzene as raw materials.
