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 ]
Methyl tert-butyl ether (MTBE), now outlawed in many states of the U.S. for road use because of water contamination. Tertiary amyl methyl ether (TAME) Tertiary hexyl methyl ether (THEME) Ethyl tertiary butyl ether (ETBE) Tertiary amyl ethyl ether (TAEE) Diisopropyl ether (DIPE) Antioxidants, stabilizers Butylated hydroxyanisole (BHA) Butylated ...
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.
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).
Synthese von 2,4,6-Tri-tert-butylphenol mit Isobuten. A synthesis of 2,4,6-tri-tert-butylphenol has been described that is also suitable as a teaching experiment. Methyl tert-butyl ether is used as the alkylating agent and sulfuric acid as catalyst. 2,4,6-TTBP is being obtained in 69% yield. [6] Synthese von 2,4,6-TTBP mit Methyl-tert ...
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. Isobutylene is not isolated from the olefin or refinery butene stream ...
A series of experiments were carried out in a batch reactor at the temperature range of 313-343 K to study the synthesis of tert-amyl ethyl ether from ethanol (EtOH) and 2-methyl-1-butene (2M1B) catalyzed by the NKC-9 ion-exchange resin. The suitable reaction pressure was obtained by using the method of the Gibbs free energy minimization. The ...
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.
