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.
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]
Acetone is a vaporization additive, mainly used with methanol racing fuel; Butyl rubber (as polyisobutylene succinimide, detergent to prevent fouling of diesel fuel injectors) Ferrous picrate, used in diesel fuel to increase fuel conversion efficiency and reduce emissions; Two-stroke oil, for lubrication of small engines reliant on crankcase ...
Methyl tert-butyl ether (MTBE) is used as a gasoline additive, as well as in various industrial manufacturing processes. The compound has contaminated groundwater and soil across the U.S., and its use has been banned in some states, including California and New York. (See MTBE controversy.) EPA included MTBE on its first Contaminant Candidate ...

The demand for ethanol produced from field corn was spurred by the discovery that methyl tertiary butyl ether (MTBE) was contaminating groundwater. [25] [28] MTBE's use as an oxygenate additive was widespread due to mandates in the Clean Air Act amendments of 1992 to reduce carbon monoxide emissions. MTBE in gasoline had been banned in almost ...
In the article it is stated at its first paragraph that (quote) Methyl tert-butyl ether, also known as methyl tertiary butyl ether and MTBE, is a chemical compound with molecular formula C5H12O. MTBE is a volatile, flammable and colorless liquid that is immiscible with water.
In the liquid fuel industry, oxygenates are hydrocarbon-derived fuel additives containing at least one oxygen atom [1] to promote complete combustion. [2] Absent oxygenates, fuel combustion is usually incomplete, and the exhaust stream pollutes the air with carbon monoxide, soot particles, aromatic and polyaromatic hydrocarbons, and nitrated polyaromatic hydrocarbons.
