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 ...
[2] [3] Due to the risks of widespread and costly litigation, and because MTBE use in gasoline was banned in almost 20 states by 2006, the substitution of MTBE opened a new market for ethanol fuel. [2] This demand shift for ethanol as an oxygenate additive took place at a time when oil prices were already significantly rising.
MTBE in gasoline had been banned in almost 20 states by 2006. Suppliers were concerned about potential litigation and a 2005 court decision denying legal protection for MTBE. [citation needed] MTBE's fall from grace opened a new market for ethanol, its primary substitute. [25] Corn prices at the time were around US$2 a bushel.
It turns out that MTBE is a relatively controversial compound because it is or was widely used in automobile fuels and it poses certain environmental problems. If anything, the amount of space on the political aspects is kept in check.
Toluene can be used as an octane booster in gasoline fuels used in internal combustion engines. Toluene at 86% by volume fueled all the turbo Formula 1 teams in the 1980s, first pioneered by the Honda team. The remaining 14% was a "filler" of n-heptane, to reduce the octane to meet Formula 1 fuel restrictions.
Although Europeans still use bioether additives, the U.S. Energy Policy Act of 2005 lifted a requirement for reformulated gasoline to include an oxygenate, leading to less MTBE being added to fuel. [62]
