Isobutane is an important raw material for chemical production, which is widely used in various industrial fields. In the upstream and downstream industry chain of isobutane, a variety of related products are involved. This article will detail the upstream and downstream associated products of isobutane.

1. Isobutane Upstream Associated Products

1. Natural Gas

Isobutane mainly comes from natural gas. Natural gas contains a large amount of methane, ethane, propane, isobutane and other hydrocarbon gases. High purity isobutane can be obtained from natural gas by separation and purification technology.

2. Naphtha

Naphtha is a by-product of the petroleum refining process and is mainly composed of hydrocarbons. By cracking naphtha, various light hydrocarbon gases including isobutane can be obtained.

2. the downstream related products of isobutane

1. Methyl tert-butyl ether (MTBE)

Methyl tert-butyl ether is a colorless and transparent liquid with excellent gasoline addition performance. It can be prepared by the reaction of isobutane with methanol under the action of an acidic catalyst. Methyl tert-butyl ether can increase the octane number of gasoline, improve the combustion performance of gasoline, and reduce the emission of harmful substances in automobile exhaust.

2. Butene

Butene is an important chemical raw material, which can be used to produce various chemicals, such as butadiene, butanol, butyric acid, etc. Isobutane can be converted to butene by a dehydrogenation reaction.

3. Isobutylene

Isobutylene is an unsaturated hydrocarbon that can be used to produce various chemicals, such as methyl methacrylate, isobutyraldehyde, etc. Isobutane can be converted to isobutene by a dehydrogenation reaction.

4. Propylene

Propylene is an important chemical raw material, which can be used to produce various polymers, chemicals, etc. Isobutane can be converted to propylene by a cracking reaction.

In short, isobutane has an important position in the field of chemical production raw materials, and its upstream and downstream related products are widely used in various industrial fields. By understanding the upstream and downstream related products of isobutane, we can better understand the role and value of isobutane in the chemical industry chain.
