tert-Butyl methyl ether, also known as Methyl tert-butyl ether (MtBE), is a versatile volatile organic compound (VOC) that finds extensive utilization as a fuel additive in various regions, including the United States. Its primary purpose is to enhance the octane rating of gasoline, resulting in improved engine performance. Additionally, tert-Butyl methyl ether is employed to diminish the emissions of carbon monoxide (CO) and hydrocarbons (HCs), thereby contributing to the reduction of air pollution. Moreover, it serves as a valuable solvent in industrial applications and acts as a chemical intermediate in the synthesis of diverse compounds. Due to its volatile nature, tert-Butyl methyl ether readily enters the atmosphere upon release. Once present in the atmosphere, it undergoes oxidation by hydroxyl radicals, resulting in the formation of methyl tert-butyl ether hydroperoxide. Further degradation of this hydroperoxide yields various byproducts, including formaldehyde, among others. These byproducts subsequently undergo additional degradation processes, such as photolysis, ultimately leading to the generation of carbon dioxide and water.
