Methyl tert-butyl ether (MTBE) was once considered an irreplaceable high-octane gasoline component and was called the “third generation of petrochemicals” in the 1980s. Because it can increase the oxygen content of unleaded gasoline, make gasoline burn more fully, reduce the emission of harmful substances such as carbon monoxide and benzene, and can replace tetraethyl lead as an anti-knock agent, it meets the requirements for the production of high-octane unleaded gasoline, resulting in a rapid increase in its demand. It is an ideal Chemicalbook high-octane gasoline additive. MTBE is an ideal blending component for the production of unleaded, high-octane, oxygenated gasoline. It can not only effectively increase the octane number of gasoline, but also improve automobile performance, reduce the CO content in exhaust gas, and reduce the cost of gasoline production. In addition, methyl tert-butyl ether is also an important chemical raw material, which can be re-cracked into isobutylene as a raw material for rubber and other chemical products. However, MTBE is currently undergoing significant capacity reduction.
