Methyl tert-butyl ether (also known as MTBE and tert-butyl methyl ether) is an organic compound with a structural formula (CH3)3COCH3. MTBE is a volatile, flammable, and colorless liquid that is sparingly soluble in water. It has a minty smell vaguely reminiscent of diethyl ether, leading to unpleasant taste and odor in water. MTBE is a blending component of gasoline, used as an oxygenate to raise the octane number and to replace lead. Wikipedia
