Exempel på hur man kan använda MTBE i en mening

• A test of the groundwater conducted on September 14, 2001, showed that the water contained the ether MTBE (methyl tertiary-butyl ether) at levels of over 350 ppb (parts per billion).
• MTBE has been used in gasoline at low levels since 1979, replacing tetraethyllead (TEL) as an antiknock (octane rating) additive to prevent engine knocking.
• Gasoline additives methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE), respectively, are produced by reacting methanol or ethanol with isobutylene contained in butene streams from olefin steam crackers or refineries, or with isobutylene from dehydrated TBA.
• Typically, one of the phases will be aqueous, and the other a lipophilic organic solvent such as ether, MTBE, dichloromethane, chloroform, or ethyl acetate.
• Ferrierite-H can be used as a catalyst in the chemical industry for the acid-catalyzed skeletal isomerization of n-butenes to isobutene, the raw material for production of methyl tert-butyl ether (MTBE).
• In reality, most fuels consist of a combination of heptane, octane, a handful of other alkanes, plus additives including detergents, and possibly oxygenators such as MTBE (methyl tert-butyl ether) or ethanol/methanol.
• Some of the molecules that are cometabolically degraded by bacteria are xenobiotic, persistent compounds, such as PCE, TCE, and MTBE, that have harmful effects on several types of environments.
• The demand for bioethanol fuel in the United States was stimulated by the discovery in the late 90s that methyl tertiary butyl ether (MTBE), an oxygenate additive in gasoline, was contaminating groundwater.
• The title of the book came from the subject line of a "memo" in the book from KTI R & D director Otto Wirk to company president Scott Nolan Hollerith sheepishly explaining that the organization's latest product had an MTBE (Mean Time Between Explosions) of only 100 hours.
• This list covers hyperaccumulators, plant species which accumulate, or are tolerant of radionuclides (Cd, Cs-137, Co, Pu-238, Ra, Sr, U-234, 235, 238), hydrocarbons and organic solvents (Benzene, BTEX, DDT, Dieldrin, Endosulfan, Fluoranthene, MTBE, PCB, PCNB, TCE and by-products), and inorganic compounds (Potassium ferrocyanide).
• In the 1980s, a fluid catalytic cracker, an alkylation unit, a visbreaker, and an MTBE (Methyl tert-butyl ether) unit (for high octane petrol) were added.
• As a member of the Air Resources Board, DeSaulnier supported strong environmental regulations, including cleaner-burning gasoline, lower-emission vehicles (LEVs), the identification of diesel exhaust as a toxic air contaminant, dioxin monitoring in the Bay Area, the banning of methyl tertiary-butyl ether (MTBE) in gasoline, the identification of secondhand smoke as a carcinogen, the reduction of emissions from dairy farms, the phase-out of rice straw in the central valley, and the reduction of emissions from cruise ships.
• The remediation of certain organic substances such as chlorinated solvents (trichloroethene and tetrachloroethene), and gasoline-related compounds (benzene, toluene, ethylbenzene, MTBE, and xylenes) by ISCO is effective.
