Methyl tert-butyl ether (MTBE) is a highly flammable, oxygen-rich organic compound widely utilized as a gasoline additive since the early 1980s. Its primary function is to enhance the octane rating of fuel and increase its oxygen content, resulting in cleaner combustion and lower emission levels. MTBE plays a crucial role in reducing air pollutants and improving overall fuel performance in modern unleaded gasoline formulations.
