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 ]
Chemical structure of chloromethyl methyl ether (MOM-Cl) Chloroalkyl ethers are a class of organic compounds with the general structure R-O-(CH 2) n-Cl, characterized as an ether connected to a chloromethyl group via an alkane chain. Chloromethyl methyl ether (CMME) is an ether with the formula C H 3 OCH 2 Cl.
tert-Butyl alcohol is used as a solvent, ethanol denaturant, paint remover ingredient, and gasoline octane booster and oxygenate.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.
The safety data sheet for a 2003 Texan unleaded gasoline shows at least 15 hazardous chemicals occurring in various amounts, including benzene (up to five percent by volume), toluene (up to 35 percent by volume), naphthalene (up to one percent by volume), trimethylbenzene (up to seven percent by volume), methyl tert-butyl ether (MTBE) (up to 18 ...
Isobutane is oxidized to tert-butyl hydroperoxide, which is subsequently reacted with propylene to yield propylene oxide. The tert-butanol that results as a by-product is typically used to make gasoline additives such as methyl tert-butyl ether (MTBE).
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.
The effect of the tert-butyl group on the progress of a chemical reaction is called the Thorpe–Ingold effect illustrated in the Diels-Alder reaction below. Compared to a hydrogen substituent, the tert-butyl substituent accelerates the reaction rate by a factor of 240. [2] tert-Butyl effect. The tert-butyl effect is an example of steric hindrance.
Tetramethylbutane, sometimes called hexamethylethane, is a hydrocarbon with formula C 8 H 18 or (H 3 C-) 3 C-C(-CH 3) 3.It is the most heavily branched and most compact of the octane isomers, the only one with a butane (C4) backbone.
