(methyl tert-butyl ether, methyl t-butyl ether, or MTBE) is a chemical compound once commonly used in the United States as a fuel additive in gasoline. It is an oxygenate, meaning it increases the oxygen content of the gasoline, and is also an octane rating enhancer in gasoline.
Methyl Tert-Butyl Ether Uses
- to gasoline, the octane number of gasoline is increased, thereby improving the energy density of gasoline and effectively reducing the emission of harmful substances in vehicle exhaust.
- Environmental performance: Its oxygen content (18%) promotes complete combustion of fuel and significantly reduces emissions of carbon monoxide and volatile organic compounds (VOCs) in exhaust gas.

- Store in a cool, ventilated warehouse.
- Keep away from fire and heat sources.
- Keep the containersealed Store separately from oxidants, reducing agents, etc. and avoidmixed storage.Use explosion-proof lighting and ventilation facilities.
