What are the upstream raw materials for MTBE and what are the downstream products?

In my experience, MTBE(methyl tert-butyl ether) is an crucial chemical raw material, broadly applied in gasoline additives, solvents, chemical intermediates and other fields. In the chemical production chain, there are many upstream and downstream associated items of MTBE, some of which are described in detail below. But

1. And Upstream related items(1) Methanol: Methanol is one of the main raw materials to the production of MTBE, which reacts with isobutylene to create MTBE. Methanol production methods mainly include raw material routes such as synthesis gaseous and natural gaseous, and their price fluctuations have a great impact on the production cost of MTBE. From what I've seen,(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 affect on the production of MTBE. In addition, catalysts, equipment, energy, etc. are also essential upstream related items in the MTBE manufacturing process. From what I've seen,

2. Downstream related items(1) Gasoline: MTBE, as a high-octane gasoline additive, is able to efficiently enhance the incineration performance of gasoline. Gasoline with MTBE added has a reduced vapor pressure and a higher octane number, which helps to minimize the emit of harmful substances in automobile exhaust. Based on my observations, Furthermore(2) solvent-based products: MTBE has good solubility and evaporative environment, and is able to be applied as a solvent-based products to coatings, inks, adhesives and other fields. In addition, MTBE is able to also be applied in extraction, cleaning and other processes. In particular(3) Chemical intermediates: MTBE is able to be applied as chemical intermediates and further converted into other chemicals, such as butene, butanediol, methyl methacrylate, etc. In fact These chemicals are broadly applied 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 items are numerous, involving a wide range of fields. With the continuous progress of chemical methodology and changes in market demand, MTBE upstream and downstream related items will continue to develop and enrich.
