52-506: Is also alcohols' intrinsically cleaner combustion, however due to its lower energy density it is not capable of producing as much energy per gallon as gasoline. Much gasoline sold in the United States is blended with up to 10% of an oxygenating agent. This is known as oxygenated fuel and often (but not entirely correctly, as there are reformulated gasolines without oxygenate) as reformulated gasoline. Methyl tert -butyl ether (MTBE)
65-411: Is different from Wikidata All article disambiguation pages All disambiguation pages Diisopropyl ether Diisopropyl ether is a secondary ether that is used as a solvent . It is a colorless liquid that is slightly soluble in water, but miscible with organic solvents. It is used as an extractant and an oxygenate gasoline additive . It is obtained industrially as a byproduct in
78-591: Is generally tested for the presence of peroxides. It is recommended once every 3 months for diisopropyl ether compared to once every 12 months for ethyl ether. Peroxides may be removed by shaking the ether with an aqueous solution of iron(II) sulfate or sodium metabisulfite . For safety reasons, methyl tert -butyl ether is often used as an alternative solvent. Oxygenate In the liquid fuel industry, oxygenates are hydrocarbon -derived fuel additives containing at least one oxygen atom to promote complete combustion . Absent oxygenates, fuel combustion
91-431: Is sometimes called (especially in military NBC/ABC/WMD contexts) IPE, a European type of I-beam Île-du-Prince-Édouard, that is, Prince Edward Island , a province of Canada Ideal polarized electrode, a type of ideal electrode Icosahedral prism , a type of polytope in geometry iris pigment epithelium , a one-cell-thick layer of cuboidal cells lying behind the iris of the eye Pyrenean Ecology Institute ,
104-669: Is usually incomplete , and the exhaust stream pollutes the air with carbon monoxide , soot particles, aromatic and polyaromatic hydrocarbons , and nitrated polyaromatic hydrocarbons. The most common oxygenates are either alcohols or ethers , but ketones and aldehydes are also included in this distinction. Carboxylic acids and esters can be grouped with oxygenates in the simple definition that they contain at least one oxygen atom. However, they are usually unwanted in oils, and therefore likely fuels, due to their environmental toxicity and tendency to cause catalyst poisoning and corrosion during oil production and refining. In
117-648: The United States , the Environmental Protection Agency (EPA) had authority to mandate that minimum proportions of oxygenates be added to automotive gasoline on regional and seasonal basis from 1992 until 2006 in an attempt to reduce air pollution, in particular ground-level ozone and smog . As of 2023, the EPA continues to require the use of oxygenated gasoline in certain areas during winter to regulate carbon monoxide emissions; however,

Institute of Public Enterprise in India Integrity Policy Enforcement, a Linux Security Module (LSM) that enables additional security features International Petroleum Exchange (old name), that is, Intercontinental Exchange Futures (ICE Futures),
143-699: The laboratory, diisopropyl ether is useful for recrystallizations because it has a wide liquid range. Diisopropyl ether is used for converting bromoboranes, which are thermally labile, into isopropoxy derivatives. Diisopropyl ether forms explosive peroxides upon standing in air. This reaction proceeds more easily than for ethyl ether due to the increased lability of the C-H bond adjacent to oxygen. Many explosions have been known to occur during handling or processing of old diisopropyl ether. Some laboratory procedures recommend use of freshly opened bottles. Antioxidants can be used to prevent this process. The stored solvent

#1732787781599156-446: The production of isopropanol by hydration of propylene . Diisopropyl ether is sometimes represented by the abbreviation DIPE. Whereas at 20 °C, diethyl ether will dissolve 1% by weight water, diisopropyl ether dissolves 0.88%. Diisopropyl ether is used as a specialized solvent to remove or extract polar organic compounds from aqueous solutions, e.g. phenols, ethanol, acetic acid. It has also been used as an antiknock agent . In
169-496: The programs to fulfill its conditions are implemented by the states. In addition to this North American automakers from 2006 onwards promoted a blend of 85% ethanol and 15% gasoline, marketed as E85 , and their flex-fuel vehicles, e.g. GM 's Live Green, Go Yellow campaign. US Corporate Average Fuel Economy (CAFE) standards give an artificial 54% fuel efficiency bonus to vehicles capable of running on 85% alcohol blends over vehicles not adapted to run on 85% alcohol blends.
