Is methyl tertiary butyl ether (MTBE) an important additive of gasoline?

Sep 18, 2025 Leave a message

Methyl tert-butyl ether (MTBE) is a gasoline additive, and it acts as a catalyst in gasoline combustion-similar to camphor, this MTBE fuel additive assists gasoline in full combustion, helping break it down into water and carbon dioxide.​
 

The main roles of Methyl tert-butyl ether (MTBE) as a gasoline additive include:​

  • Improving octane number: The MTBE additive has a high octane number (around 118). When blended into gasoline, it can effectively enhance anti-knock performance, making engines run more smoothly and extending their service life.​
  • Reducing exhaust pollution: The oxygen-containing property of this gasoline additive MTBE promotes full combustion of gasoline, lowering emissions of carbon monoxide (CO) and unburned hydrocarbons (HC), which meets environmental regulation requirements.​
  • Cost and process advantages: MTBE in fuel is easy to produce and relatively low in price. It has been widely used to replace toxic tetraethyl lead as an octane improver. Besides serving as an MTBE additive, it also functions as an MTBE solvent in some scenarios.
