Is MTBE soluble in water?
WaterMethyl tert-butyl ether / Soluble inWater is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth’s hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides neither food, energy, nor organic micronutrients. Wikipedia
What type of compound is MTBE?
Methyl tertiary-butyl ether (MTBE), also known as methyl tert-butyl ether and tert-butyl methyl ether, is an organic compound with a structural formula (CH3)3COCH3. MTBE is a volatile, flammable, and colorless liquid that is sparingly soluble in water.
What kind of solvent is MTBE?
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.
What functional group is MTBE?

Why is MTBE soluble in water?
MTBE is comprised of a methyl (CH3 group) bonded by an oxygen atom to a butyl (C4H9) group. The C-O-C linkage makes this compound an ether. Ethers are generally hydrophilic (water- loving) and are therefore very soluble in water. For example, the solubility of pure MTBE in water is 50,000 mg/L.
What do you know about MTBE?
What is MTBE? MTBE(methyl tertiary-butyl ether) is a chemical compound that is manufactured by the chemical reaction of methanol and isobutylene. MTBE is produced in very large quantities (over 200,000 barrels per day in the U.S. in 1999) and is almost exclusively used as a fuel additive in motor gasoline.
Is MTBE denser than water?
MTBE has a specific gravity of 0.740, which is even less than the BTEX compounds. Therefore, as it is less dense than water it can not ‘sink’.
Is MTBE volatile?
Trihalomethanes, solvents, and gasoline oxygenates are the most commonly detected volatile organic compounds in ambient ground water. The detection frequency of MTBE in ambient ground water is highest in urban land use.
How does MTBE get in water?
Releases of MTBE to ground and surface water can occur through leaking underground storage tanks and pipelines, spills, emissions from marine engines into lakes and reservoirs, and to some extent from air deposition.
Why is MTBE a good solvent?
MTBE is a more polar solvent compared to chloroform and has a substantial higher capacity for solubilizing water (1.4 %) without phase separation (Watanabe et al. 2007). This results in higher water content in the lipid-containing organic phase, which improves the extraction efficiency for acidic lipid classes.
What is the chemical formula for MTBE?
C5H12OMethyl tert-butyl ether / Formula
Methyl tertiary-butyl ether (MTBE), also known as methyl tert-butyl ether and tert-butyl methyl ether, is an organic compound with a structural formula (CH3)3COCH3. MTBE is a volatile, flammable, and colorless liquid that is sparingly soluble in water.
How does MTBE get into groundwater?
MTBE can be released to groundwater by leaking underground storage tanks and piping, atmospheric deposition, spills during transportation, and leaks at refineries. Underground storage tank or piping releases make up the majority of the releases that have impacted groundwater.
