Upstream and downstream related products
of industrial butadiene
butadiene is an important chemical raw material, widely used in synthetic rubber, plastics, fibers and other fields. In the production process of industrial butadiene, its upstream and downstream related products also have an important position. This article will introduce the upstream and downstream associated products of butadiene.

1. upstream associated products

1. Petroleum pyrolysis gas

Petroleum pyrolysis gas is one of the main raw materials for industrial butadiene. Petroleum pyrolysis gas contains a large number of olefins, including butadiene. Through separation and purification, high purity butadiene can be obtained from petroleum pyrolysis gas.

2. Ethanol

ethanol can also be used to produce butadiene. Through the ethanol dehydrogenation reaction, butadiene and other by-products can be produced. However, the production cost of this method is high, so it is not the main production method of industrial butadiene.

2. downstream related products

1. Synthetic rubber

Butadiene is one of the important monomers of synthetic rubber, can be used to produce butadiene rubber, styrene butadiene rubber, nitrile rubber and other synthetic rubber. These synthetic rubbers are widely used in tires, hoses, tapes, sealing products and other fields.

2. Plastic

Butadiene can also be used to produce plastics, such as polybutadiene, acrylonitrile-butadiene-styrene copolymer (ABS), etc. These plastics have excellent mechanical properties, chemical corrosion resistance, heat resistance, etc., and are widely used in home appliances, automobiles, construction and other fields.

3. Fiber

Butadiene can be used in the production of synthetic fibers, such as polyester, acrylic and so on. These synthetic fibers have excellent elasticity, wear resistance, wrinkle resistance and other properties, and are widely used in clothing, home textiles, industrial textiles and other fields.

In short, the upstream and downstream related products of industrial butadiene are extensive, involving many fields, and play an important role in the development of the chemical industry.
