It is an ideal blending component for the production of lead-free, high-octane, oxygenated gasoline. Its steam is heavier than air, can diffuse along the ground, and can burn when coexisting with strong oxidants. As a gasoline additive, it has been widely used all over the world. It can not only effectively increase gasoline octane number, but also improve vehicle performance, reduce CO content in exhaust gas, and reduce gasoline production costs. In addition, MTBE is also an important chemical raw material, for example, high-purity isobutene can be produced by cracking.
