MTBE is used in organic chemistry as a relatively inexpensive solvent with properties comparable to diethyl ether, but with a higher boiling point and less solubility in water. As a solvent, MTBE has one distinct advantage over most ethers - it has a much lower tendency to form explosive organic peroxides.
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 ...
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 ...
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.
The US is the world's largest producer of ethanol, having produced nearly 16 billion gallons in 2017 alone. [1] The United States, together with Brazil accounted for 85 percent of all ethanol production, with total world production of 27.05 billion gallons.
Summary of the main ethanol blends used around the world in 2013. Several common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in internal combustion engines (ICEs) is only possible if the engines are designed or modified for that purpose, and used only in automobiles, light-duty trucks and motorcycles.
Until 2005 Brazil was the world's top producer of ethanol fuel when it was surpassed by the United States. Together both countries were responsible in 2011 for 87.1% of the world's ethanol fuel production. [1] In 2009 Brazil produced 27.5 billion liters (7.26 billion U.S. liquid gallons), [13] representing 35.9% of the world's total ethanol ...
