Applicazioni

tert-Butyl ethyl ether is used as an oxygenate gasoline additive oxygenate during its production from crude oil. It is used as an extractant in human urine by using single-walled carbon nanotubes as an adsorbent. It plays an important role as a fuel component in petrol to enhance its octane rating.

Note

Incompatible with strong oxidizing agents, neoprene, n-butyl and urethane. It may react with air to form peroxides.
