MTBE (methyl tert-butyl ether) is an important chemical raw material, widely used in gasoline additives, solvents, chemical intermediates and other fields. In the chemical production chain, there are many upstream and downstream associated products of MTBE, some of which are described in detail below.

1. Upstream Associated Products

(1) Methanol: Methanol is one of the main raw materials for the production of MTBE, which reacts with isobutylene to generate MTBE. Methanol production methods mainly include raw material routes such as synthesis gas and natural gas, and their price fluctuations have a great impact on the production cost of MTBE.

(2) Isobutene: Isobutene is another main raw material of MTBE, which is mainly produced by naphtha cracking or propylene dehydrogenation. The supply stability and price of isobutene have a great influence on the production of MTBE.

In addition, catalysts, equipment, energy, etc. are also essential upstream related products in the MTBE production process.

2. Downstream related products

(1) Gasoline: MTBE, as a high-octane gasoline additive, can effectively improve the combustion performance of gasoline. Gasoline with MTBE added has a lower vapor pressure and a higher octane number, which helps to reduce the emission of harmful substances in automobile exhaust.

(2) Solvent: MTBE has good solubility and volatility, and can be used as a solvent for coatings, inks, adhesives and other fields. In addition, MTBE can also be used in extraction, cleaning and other processes.

(3) Chemical intermediates: MTBE can be used as chemical intermediates and further converted into other chemicals, such as butene, butanediol, methyl methacrylate, etc. These chemicals are widely used in plastics, rubber, fibers, surfactants and other fields.

In short, MTBE has a connecting role in the field of chemical production raw materials, its upstream and downstream related products are numerous, involving a wide range of fields. With the continuous progress of chemical technology and changes in market demand, MTBE upstream and downstream related products will continue to develop and enrich.
