Methyl tert-butyl ether (MTBE) - High-Octane Gasoline Additive from Trusted China Suppliers and Factory

Methyl tert-butyl ether (MTBE) is a clear, colorless liquid that is commonly utilized as a high-octane gasoline additive, enhancing both octane ratings and anti-knock performance. This compound is insoluble in water, but it dissolves easily in ethanol and diethyl ether, making it a versatile choice for various applications. Renowned for its low vapor pressure and excellent evaporation properties, MTBE contributes superior volatility and combustion efficiency to gasoline formulations. As a leading supplier and manufacturer based in China, our factory produces high-quality MTBE to meet the demands of the automotive and fuel industries
  • CAS 1634-04-4
