Cumene 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 main upstream and downstream related products of cumene.

upstream products:

1. Propylene: Propylene is one of the main raw materials of cumene. It reacts with benzene to produce cumene through alkylation. The production methods of propylene mainly include steam cracking, catalytic cracking, propane dehydrogenation, etc.
2. Benzene: Benzene is another important raw material of cumene. It is alkylated with propylene to obtain cumene. Benzene mainly comes from the separation of aromatic hydrocarbons in petrochemical processes.

Downstream Products:

1. Phenol: Cumene can be converted to phenol through oxidation reaction. Phenol is an important organic chemical raw material, which is widely used in the production of phenolic resin, bisphenol A, caprolactam and so on.
2. Acetone: During the oxidation of cumene, acetone is also generated. Acetone is an important solvent and organic synthesis raw material, used in the production of coatings, adhesives, pharmaceutical intermediates.
3. Cumene hydroperoxide: Cumene hydroperoxide can be obtained by the reaction of cumene and hydrogen peroxide, which is an important oxidant and can be used for epoxidation reactions and epoxidation of olefins.
4. methyl methacrylate: cumene after oxidation, esterification and other reactions can be generated methyl methacrylate, which is used in the production of organic glass, coatings, adhesives and other polymer monomers.

Through the above introduction, we can see that cumene has a wide range of upstream and downstream related products in the field of chemical production raw materials, involving many important organic chemical raw materials and intermediates.
