Methyl t-Butyl Ether (MtBE): Health Information Summary . Methyl tertiary -butyl ether (MtBE) is a colorless, synthetically produced liquid. Most people can smell MtBE in water at relatively low concentrations. Depending on the level in water, the odor has been described as "sweet, solvent-like, alcohol, or turpentine."

PERSPECTIVES ON SPECIFIC SUBSTANCES: METHYL tert-BUTYL ETHER 34.3 FIGURE 34.1 Annual spill frequency of gasoline with MTBE (7–15%) 1985–1991. • It lowers the gasoline 50% ignition point, thus enhancing cold engine warmup perform- ance. • Its relatively low taste and odor thresholds provide ample warning of its presence. • It has very low toxicity and does not bioaccumulate.
Methyl tertiary butyl ether (MTBE) is a volatile organic compound (VOC) commonly used as a gasoline additive. MTBE is also known as methyl t-butyl ether, methyl tert butyl ether, and 2-methoxy-2-methylpropane. The Chemical Abstracts Service (CAS) registry number for MTBE is 1634-04-4. It does not have any common trade names.
The purpose of this section is to list the chemicals for which primary maximum contaminant levels ( MCLs ) have been established to protect the health of consumers of drinking water served by community and nontransient-noncommunity water systems. Methyl tert-butyl ether (MTBE) would be added to this list (Table 64444-A) with a

Methyl tert -butyl ether. MTBE is a volatile, flammable, and colorless liquid that is sparingly soluble in water. It has a minty odor vaguely reminiscent of diethyl ether, leading to unpleasant taste and odor in water. MTBE is a gasoline additive, used as an oxygenate to raise the octane number.
Whether use of oxygen-rich gasoline additives to reduce air pollution is a cause of acute adverse health effects is an ongoing concern in the United States. Attention has focused in particular on use of methyl tert-butyl ether (MTBE, CAS #1634-04-4) and, despite considerable published research, debate persists regarding its potential for .
Methyl tert-butyl ether (MTBE) is a flammable liquid with a distinctive, disagreeable odor. It is made from blending chemicals such as isobutylene and methanol, and has been used since the 1980s as an additive for unleaded gasolines to achieve more efficient burning. MTBE is also used to dissolve gallstones.
Methyl tert-butyl ether is a gasoline additive used as an oxygenate and to raise the octane number. Its use has declined in the United States in response to environmental and health concerns. It has polluted groundwater due to MTBE-containing gasoline being spilled or leaked at gas stations. MTBE spreads more easily underground than other gasoline components due to its higher solubility in water. Cost estimates for removing MTBE …
