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 ]
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 EPA also regularly reviews the health and net economic benefits of Clean Air Act policies. [9] The act also requires deposit control additives (DCAs) be added to all petrol. This type of additive is a detergent additive that acts as a cleansing agent in small passages in the carburetor or fuel injectors.
Iron pentacarbonyl, also known as iron carbonyl, is the compound with formula Fe(CO) 5. Under standard conditions Fe(CO) 5 is a free-flowing, straw-colored liquid with a pungent odour. This compound is a common precursor to diverse iron compounds, including many that are useful in organic synthesis . [ 20 ]
Isobutylene can also be produced in high purities by "back-cracking" MTBE or ETBE at high temperatures and then separating the isobutylene by distillation from methanol. Isobutylene is a byproduct in the ethenolysis of diisobutene to prepare neohexene : [ 5 ]
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.
In situ chemical oxidation (ISCO), a form of advanced oxidation process, is an environmental remediation technique used for soil and/or groundwater remediation to lower the concentrations of targeted environmental contaminants to acceptable levels.
Ethyl tertiary-butyl ether (ETBE), also known as ethyl tert-butyl ether, is commonly used as an oxygenate gasoline additive in the production of gasoline from crude oil.ETBE offers equal or greater air quality benefits than ethanol, while being technically and logistically less challenging.
