What is methyl tert-butyl ether CAS 1634-04-4 ?

MTBE (methyl tert-butyl ether) also known as Tert-Butyl Methyl Ether. It is a high-octane gasoline additive. The chemical oxygen content is much lower than that of methanol, which is beneficial to warming up the car and saving fuel. It has low latent heat of evaporation. Good for cold start, often used in blending of unleaded gasoline and low lead oil. It can also be re-cracked into isobutylene as a raw material for rubber and other chemical products. The best quality methyl tert-butyl ether can be used as medicine and is a medicine intermediate.

Is MTBE still used in gasoline?

MTBE is no longer used in gasoline in the United States and has been significantly phased out in most parts of the world. However, it is still used in some other countries.

 

In the U.S., the Clean Air Act's RFG program initially mandated oxygenates, but MTBE was largely replaced by ethanol after states like California banned it in 2003 (due to groundwater contamination). The European Union (EU) also restricted MTBE use in gasoline, with most countries adopting ethanol or other oxygenates. Canada and Australia have similarly reduced MTBE use in favor of ethanol-blended gasoline.

 

MTBE remains in gasoline in parts of Asia (e.g., China, India, and some Southeast Asian countries) and the Middle East. In these regions, ethanol production may be limited
