MTBE as a Fuel Oxygenate and Solvent
Methyl tert-butyl ether (MTBE, CAS 1634-04-4) boosts octane and adds oxygen to gasoline, improving combustion and reducing carbon monoxide emissions in petrol engines. Outside fuel blending, MTBE is a versatile extraction solvent for recovering high-purity products and a reaction medium in fine chemistry.
