A plan to assess the occurrence and distribution of methyl tert-butyl ether (MTBE) and other volatile organic compounds (VOCs) in drinking water and ambient ground water in the Northeast and Mid-Atlantic regions of the United States was designed to meet two primary objectives. This study will provide the U.S. Environmental Protection Agency with information on potential human exposure to MTBE. 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).
The extract was then diluted with μL of pure water and vortexed before adding μL of 1 M potassium hydroxide. The tube was vortexed and then supplemented with 7 mL of methyl tert-butyl ether, then placed in a mechanical shaker for 20 minutes followed by centrifugation. The organic layer was subsequently transferred into a clean. oxygen requirements, the alkyl ether methyl tert-butyl ether (MTBE) has been, and continues to be, the most commonly used oxygenate. As of , MTBE was used in more than 80 percent of oxygenated gasoline. Recent information indicates that MTBE is the most frequently used gasoline oxyg enate in .
Methyl tertiary-butyl ether (MTBE) is an oxygenated compound added to gasoline to improve air quality as part of the US Federal Clean Air Act. Due .

Arp and, Torsten C. by: Briefly, five grams of sediment was transferred to a 50 mL PP centrifuge tube, and vortexed with 2 mL of cleaned Mill-Q water. 2 mL of M Na 2 CO 3 and 1 mL of M tetrabutylammonium hydrogensulfate (TBAHS, HPLC grade) solutions were then added and vortex mixed before duplicate extraction with methyl tert-butyl ether (MTBE, HPLC grade.
Methyl tert-butyl ether (MTBE) is widely used as gasoline oxygenate and octane number enhancer for more complete combustion in order to reduce the air pollution caused by motor vehicle exhaust. Using the standard method and column for quantification, only one of the potential mimics co-eluted with DEET during analysis, N-(1-methyl-butyl)-benzamide, a second candidate, N-tert-butylmethyl-benzamide, was not baseline resolved with the peak corresponding to DEET.
