With an octane number reaching up to 110, MTBE effectively enhances gasoline’s resistance to knocking (detonation), making it suitable for high-compression ratio engines and improving fuel efficiency.
Features a low boiling point and high volatility. It exhibits excellent miscibility with gasoline and improves engine cold-start performance in low-temperature environments.
Remains chemically stable at room temperature and does not easily decompose, making it suitable for long-term storage. It is also unlikely to undergo adverse reactions with other chemical raw materials.
As a core additive for unleaded gasoline, Methyl Tertiary Butyl Ether (MTBE) is blended into gasoline at a ratio of 5%–15% to boost the octane number and reduce carbon deposits in engines. Empirical data indicates that gasoline containing 10% MTBE can reduce fuel consumption by 7% and significantly lower exhaust emissions of lead, carbon monoxide, and carcinogenic polycyclic aromatic hydrocarbons (PAHs).
Case Study: In 2025, a major domestic refinery utilized AOLANSU's MTBE to formulate high-octane gasoline. The resulting product achieved a 100% compliance rate with quality standards, helping the refinery successfully obtain certification for China's “National VI” (Euro 6 equivalent) emission standards and achieving a reduction in exhaust pollutant emissions of over 15%.
As a key intermediate, MTBE is utilized in the production of tert-butanol and high-purity isobutylene (generated via cracking), which are subsequently synthesized into products such as butyl rubber, polyisobutylene, and methyl methacrylate.
Case Study: A chemical enterprise in Shandong leveraged its local production capacity to procure AOLANSU MTBE. By cracking the MTBE to produce high-purity isobutylene for butyl rubber manufacturing, the company achieved a product purity of 99.9%, thereby meeting the stringent production requirements for high-end tire sealing materials.
Owing to its excellent solvency, Methyl Tertiary Butyl Ether is widely employed in the production of coatings, inks, adhesives, cleaning agents, and fine chemicals. It is capable of dissolving substances such as resins, rubber, and greases, while leaving no residue upon evaporation and improving the surface finish of final products.
Case Study: A coatings manufacturer in Guangdong utilized AOLANSU MTBE to replace traditional toxic solvents in the production of eco-friendly water-based coatings. This transition resulted in a 30% reduction in VOC content, enabled the company to obtain EU environmental certification, and led to a 40% increase in export orders.
