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.
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 ...
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.
Typical agents that have been used for their antiknock properties are: Tetraethyllead (still in use as a high octane additive) MTBE; Ethanol; Methylcyclopentadienyl manganese tricarbonyl (MMT) Ferrocene; Iron pentacarbonyl; Toluene; Isooctane; BTEX - a hydrocarbon mixture of benzene, toluene, xylene and ethyl-benzene, also called gasoline ...
As of 2005, it was somewhat more expensive than fossil diesel, though it is still commonly produced in relatively small quantities, in comparison to petroleum products and ethanol fuel. Biofuels are mainly used mixed with fossil fuels. They are also used as additives. The largest biodiesel consumer is the U.S. Army.
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.
