Methyl tert-butyl ether (MTBE), also known as tert-butyl methyl ether, is an organic compound with a structural formula (CH 3) 3 COCH 3. MTBE is a volatile, flammable, and colorless liquid that is sparingly soluble in water. [ 1 ]
The MTBE controversy concerns methyl tert-butyl ether (MTBE), a gasoline additive that replaced tetraethyllead.MTBE is an oxygenate and raises gasoline's octane number.Its use declined in the United States in response to environmental and health concerns.

Methylibium petroleiphilum is a species of methyl tert-butyl ether-degrading methylotroph, the type species of its genus. It is a Gram-negative , rod-shaped, motile , non-pigmented, facultative aerobe, with type strain PM1 T (=ATCC BAA-1232 T =LMG 22953 T ).
This is known as oxygenated fuel and often (but not entirely correctly, as there are reformulated gasolines without oxygenate) as reformulated gasoline. Methyl tert-butyl ether (MTBE) was the most common fuel additive in the United States, prior to government mandated use of ethanol. Typically, gasoline with added MTBE is called reformulated ...
Tetraethyl lead was largely replaced in the US with methyl tert-butyl ether starting in 1979. MTBE is a toxic water pollutant, and a series of groundwater contamination scandals starting in the 90's prompted the EPA to begin phasing MTBE out in 2000.

Gasoline additives methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE), respectively, are produced by reacting methanol or ethanol with isobutylene contained in butene streams from olefin steam crackers or refineries, or with isobutylene from dehydrated TBA. Isobutylene is not isolated from the olefin or refinery butene stream ...
