Diethyl benzene has an important position in the field of chemical production raw materials, and its upstream and downstream related products are extensive. The following describes in detail the main upstream and downstream associated products of diethylbenzene.

upstream products:

1. Benzene: Benzene is one of the main raw materials of diethylbenzene, which is alkylated with ethylene to produce diethylbenzene. Benzene is a basic chemical raw material, widely used in synthetic rubber, plastic, fiber and other fields.
2. Ethylene: Ethylene is another main raw material of diethylbenzene, which is alkylated with benzene to produce diethylbenzene. Ethylene is an important petrochemical raw material, mainly used in the production of polyethylene, ethylene propylene rubber, ethanol and other products.

downstream products:

1. Styrene: diethylbenzene can be further reacted to generate styrene, which is an important organic chemical raw material, mainly used in the production of polystyrene, styrene-acrylonitrile copolymer and other plastic materials, as well as functional polymer materials such as ion exchange resins.
2. Alkyl benzene: Diethyl benzene can be used as an alkylating agent to alkylate with other aromatic hydrocarbons to generate different alkyl substituted alkyl benzene products, such as triethylbenzene, tetraethylbenzene, etc. These products are widely used in synthetic rubber, lubricating oil additives, solvents and other fields.
3. Ethyl phenol: Diethyl benzene can be oxidized to produce ethyl phenol. Ethyl phenol is an important fine chemical, which can be used in the production of antioxidants, pesticides, spices and other products.
4. Aniline: Diethylbenzene can undergo a series of reactions to form aniline. Aniline is an important organic chemical raw material, widely used in the synthesis of dyes, pharmaceuticals, pesticides and other fields.

Generally speaking, diethylbenzene plays a connecting role in the field of chemical production raw materials, and its upstream and downstream related products are extensive, involving plastics, rubber, fibers, dyes, medicine, pesticides and other fields.
