    Biodegradation of Methyl Tert-Butyl Ether and Other Fuel Oxygenates by a New Strain, Mycobacterium austroafricanum IFP Exit Published in Applied Environmental Microbiology, this paper presents research results on the effect of a methylotrophic bacterium on the biodegradation of MTBE and other oxygenates. methyl tert-butyl ether (MTBE) typically found in drinking water wells. September Methyl tert-butyl ether (MTBE) What is methyl tert-butyl ether? Methyl tert-butyl ether (MTBE) is a synthetic flammable liquid with a distinctive, disagreeable odor. Since the s, adding MTBE to unleaded gasoline has helped make it burn more efficiently.

    Nov 07,  · Methyl tert-butyl ether (also known as MTBE, tert-butyl methyl ether, tertiary butyl methyl ether and tBME) is an organic compound with structural formula (CH3)3COCH3. There will be scheduled maintenance work beginning on Wednesday 26th February from AM through to PM (GMT).. During this time, you may not be able to log into ChemSpider. We apologise for any inconvenience this might cause and thank you for your patience.

    The wide-scale use of methyl tertiary butyl ether (MTBE) in gasoline has resulted in substantial public controversy and action to ban or control its use due to perceived impacts on water quality. Because oxygenates are still required under federal law, considerable research has focused on ethanol as a substitute for erum-c.com by: BUTYL METHYL ETHER can act as a base to form salts or addition compounds with strong acids. May react violently with strong oxidizing agents. Oxidizes readily in air. Relatively unreactive in other reactions, which typically involve the breaking of the carbon-oxygen bond.

Methyl tert-butyl ether | C5H12O | CID - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities. 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. It has a minty smell vaguely reminiscent of diethyl ether, leading to unpleasantChemical formula: C₅H₁₂O. The National Institute of Standards and Technology (NIST) uses its best efforts to deliver a high quality copy of the Database and to Quality of methyl tert-butyl ether book that the data contained therein have been selected on the basis of sound scientific judgment.

Methyl tert-butyl ether is also called MTBE and tert-butyl methyl ether. (1,3) The chemical formula for methyl tert-butyl ether is C5H12O, and its molecular weight is g/mol. (1,4,5) Methyl tert-butyl ether occurs as a colorless liquid, with a vapor pressure of mm Hg at 25 °C.

(1,4,5). Methyl tert-butyl ether (MTBE) is the main component of ether oxygenate; as such MTBE production all over the world is in a considerable volume.

The potential exposure of humans to MTBE should be monitored. This chapter describes the reproductive and developmental toxicity of MTBE in rodents, rabbits and aquatic organisms.

Apr 07,  · Methyl tert-butyl ether (MTBE) was added to reformulated gasoline to boost octane and to reduce carbon monoxide exhaust emissions in high smog areas of the United States in thes. Because of concerns for groundwater contamination and water quality, MTBE was banned or its usage was limited in several states.

General description tert-Butyl methyl ether (MTBE) is a gasoline erum-c.com undergoes oxidative degradation in the presence of propane-oxidizing bacterial strains. The kinetic studies of heat-assisted persulfate oxidation of MTBE under various parameters suggests that the reaction follows the pseudo-first-order kinetics.
