Upstream and downstream related products
of butadiene
Butadiene is an important chemical raw material, widely used in synthetic rubber, plastics, fibers and other fields. Its upstream and downstream related products are numerous, which will be described in detail below.

upstream products:

1. Petroleum cracking gas: butadiene is mainly obtained by the separation of petroleum cracking gas, so petroleum cracking gas is the main upstream raw material of butadiene.

2. Ethylene: Ethylene is one of the main components of petroleum cracking gas, and butadiene can be obtained by ethylene cracking.

downstream products:

1. Synthetic rubber: Butadiene is one of the main raw materials of synthetic rubber, which can be used to produce butadiene rubber, styrene butadiene rubber, nitrile rubber, etc. These rubbers are widely used in tires, hoses, tapes, sealing products and other fields.

2. Plastics: Butadiene can be used to produce polybutadiene plastics, which has excellent impact resistance, wear resistance, corrosion resistance and other advantages, and can be used to manufacture high-strength, high-toughness engineering plastics.

3. Fiber: Butadiene can be used to produce butadiene fiber, which has the advantages of high strength, high modulus, light weight, etc., and can be used in the manufacture of composite materials, reinforcement materials and other fields.

4. Butanediol: Butanediol can be obtained by hydrogenation of butadiene. It is an important organic chemical raw material and can be used to produce plasticizers, stabilizers, antioxidants, etc.

In short, there are many upstream and downstream related products of butadiene, which are widely used in various fields and are of great significance to promote the development of the chemical industry.

The above is only a brief introduction to the upstream and downstream related products of butadiene. For more information, it is recommended to consult relevant literature or consult professionals.
