It is one of a group of chemicals commonly known as oxygenates because they raise the oxygen content of gasoline. It will enhance any encyclopedic page you visit with the magic of the WIKI 2 technology.

It is miscible with water, ethanol and diethyl ether. Activated carbon produced from coconut shells and optimized for MTBE adsorption may reduce MTBE to undetectable levels,[26] although this level of reduction is likely to occur only in the most ideal circumstances. Charles Babington, House Again Passes GOP Energy Measures, Washington Post, June 16, 2004, at A4 (House passes Energy Bill, but Senate opponents of MTBE provision in House Bill have the votes to prevent its enactment). Before the introduction of other oxygenates and octane enhancers, refiners chose MTBE for its blending characteristics and low cost.

[5] The resulting gases then further react in the presence of a catalyst to form methanol. EPA (1998-03-02). New York Consolidated Laws, Agriculture and Markets Law. That's it. It will enhance any encyclopedic page you visit with the magic of the WIKI 2 technology. MTBE is used as a fuel component in fuel for gasoline engines. [7], MTBE production in the U.S. peaked in 1999 at 260,000 barrels per day[8] before dropping down to about 50,000 barrels per day and holding steady,[9] mostly for the export market. [6] Isobutylene can be produced through a variety of methods. Energy Policy Act of 2005. [38] In another case, New York City estimated a $250 million cost for cleanup of a single wellfield in the borough of Queens in 2009. The Energy Policy Act of 2005, as approved by the U.S. House of Representatives, did not include a provision for shielding MTBE manufacturers from water contamination lawsuits. [40], As of 2016, hundreds of lawsuits are still pending regarding MTBE contamination of public and private drinking water supplies. [30] However, MTBE is still legal in the state for other industrial uses.[31]. Iso-octane itself is used. [7], MTBE production in the U.S. peaked in 1999 at 260,000 barrels per day[8] before dropping down to about 50,000 barrels per day and holding steady,[9] mostly for the export market. MTBE is used as a fuel component in fuel for gasoline engines. ", Last edited on 20 September 2020, at 05:23, United States Environmental Protection Agency, Institute for Occupational Safety and Health, "Methyl tertiary butyl ether prices, markets & analysis", "Hydrogen production via natural gas steam reforming in a Pd-Au membrane reactor. "Announcement of the Drinking Water Contaminant Candidate List.

[39] In 2013 a jury awarded the State of New Hampshire $236 million in damages in order to treat groundwater contaminated by MTBE. [33] Due to opposition in the Senate,[34] the conference report dropped all MTBE provisions. [2][3], MTBE is manufactured via the chemical reaction of methanol and isobutylene. According to the IARC, a cancer research agency of the World Health Organization, MTBE is not classified as a human carcinogen. We have created a browser extension. Methyl tert-butyl ether (MTBE), also known as tert-butyl methyl ether, is an organic compound with a structural formula (CH3)3COCH3. MTBE is a volatile, flammable, and colorless liquid that is sparingly soluble in water. There is limited data on the pharmacology and toxicology of tert-butanol in humans and other animals. Tert-butanol is poorly absorbed through skin but rapidly absorbed if inhaled or ingested. [32] This bill did include a provision that gave MTBE makers, including some major oil companies, $2 billion in transition assistance while MTBE was phased out over the following nine years.

Although an ether, MTBE is a poor Lewis base and does not support formation of Grignard reagents.

MTBE may be tasted in water at concentrations of 5 – 15 µg/l. The Energy Policy Act of 2005, as approved by the U.S. House of Representatives, did not include a provision for shielding MTBE manufacturers from water contamination lawsuits. MTBE may be tasted in water at concentrations of 5 – 15 µg/l. [citation needed], EPA first listed MTBE in 1998 as a candidate for development of a national Maximum Contaminant Level (MCL) standard in drinking water. In the U.S. it has been used in gasoline at low levels since 1979, replacing tetraethyllead (TEL) as an antiknock (octane rating) additive to prevent engine knocking. It has a minty smell vaguely reminiscent of diethyl ether, leading to unpleasant taste and odor in water. It has a minty odor vaguely reminiscent of diethyl ether, leading to unpleasant taste and odor in water.

2,4-Dimethyl-6-tert-butylphenol is the organic compound with the formula Me 2 (tert-Bu)C 6 H 2 OH (Me = methyl, tert-Bu = tertiary butyl). Oxygenates also help gasoline burn more completely, reducing tailpipe emissions and dilute or displace gasoline components such as aromatics (e.g., benzene).
It is a chemical intermediate used to produce methyl tert -butyl ether (MTBE) and ethyl tert -butyl ether (ETBE) by reaction with methanol and ethanol , respectively, and tert -butyl hydroperoxide (TBHP) by reaction with hydrogen peroxide .
