Butane has an important position in the field of chemical production raw materials, and its upstream and downstream related products are extensive. The upstream and downstream associated products of butane will be described in detail below.

upstream products

1. natural gas: butane is mainly separated and extracted from natural gas, so natural gas is the main upstream raw material of butane.
2. Petroleum: Petroleum also contains butane components, and butane can be obtained through petroleum processing and separation.

downstream products

1. Ethylene: Butane can produce ethylene through cracking reaction. Ethylene is an important organic chemical raw material, which is widely used in the production of plastics, fibers, rubber and other products.
2. Butene: Butane can also be dehydrogenated to produce butene, butene is an important monomer for the production of polymer compounds, can be used to produce polyethylene, polypropylene and so on.
3. Butadiene: Butane can also be oxidative dehydrogenation of butadiene, butadiene is an important raw material for synthetic rubber, synthetic resin and other polymer compounds.
4. Butanol: Butane can be hydrolyzed to produce butanol, butanol is a solvent and chemical raw materials, used in the production of plasticizers, stabilizers and so on.
5. Butyl acetate: Butanol can react with acetic acid to form butyl acetate, butyl acetate is an excellent solvent, widely used in printing inks, coatings and other fields.

In short, the upstream and downstream related products of butane are very extensive, involving many fields, such as plastics, rubber, fibers, solvents, plasticizers, etc. The production and use of these products have played an important role in promoting the development of the chemical industry.
