Methyl Tertiary Butyl Ether (MTBE) & Ethyl Tertiary Butyl Ether (ETBE)

Widely-used fuel additives

Key gasoline additives – dissect past trends and navigate shifts in demand.

With the EU Renewable Energy Directive (EU RED II) set to increase the use of biofuels in Europe, it is crucial to follow MTBE and ETBE market trends as countries fulfil EU mandates.

A colourless liquid manufactured using methanol and isobutylene, Methyl tert-butyl ether (MTBE) has been used as an anti-knocking agent for gasoline engines since the 1970s. This is when it began to replace tetraethyl lead (TEL). It cuts emissions by raising the oxygen content of gasoline so it burns more completely. It is also used in small amounts as a laboratory solvent and for some medical applications. Worldwide production exceeds 35 million tonnes.

ETBE is also an oxygenate and gasoline additive but is made from ethanol and isobutene. The price of ethanol is higher than methanol, making ETBE more expensive.
