甲基叔丁基醚简称MTBE,是一种透明、无色、高辛烷值的液体,具有醚类所特有的气味,氧含量为18%(质量分数)。MTBE能与汽油很好地互溶,是生产无铅、高辛烷值、含氧汽油的理想调合组分,其作为汽油添加剂已经在全世界范围内普遍使用。它不仅能有效提高汽油辛烷值(添加2%的MTBE汽油产品的辛烷值可增加7%)和汽油燃烧效率,汽车尾气中不含铅,而且还能改善汽车性能,同时减少了其他有害物质如臭氧、苯、丁二烯等的排放,降低汽油的成本。
MTBE, abbreviated as MTBE, is a clear, colorless, high octane liquid with an ether-specific odor with an oxygen content of 18% (mass fraction). MTBE is well miscible with gasoline and is an ideal blending component for the production of lead-free, high-octane, and oxygenated gasoline, which is commonly used as a gasoline additive worldwide. Not only does it improve the octane rating of gasoline (7% increase in octane rating with 2% MTBE petrol) and gasoline combustion efficiency, it does not contain lead in the vehicle exhaust, but it also improves vehicle performance while reducing other harmful Substance such as ozone, benzene, butadiene emissions, reduce the cost of gasoline.
