Properties
Chemical
MTBE will react with bromine.
Physical
MTBE is a volatile, flammable, and colorless liquid, poorly soluble in water.
Availability
MTBE is available as a gasoline additive.
Preparation
MTBE is produced by reacting methanol with isobutylene. It can also be synthesized by reacting tert-butanol with methyl iodide.
Projects
- Organic extractions
- Anti-knocking agent
Handling
Safety
Unlike most ethers, MTBE has a reduced tendency to form explosive organic peroxides. Opened bottles of diethyl ether or THF can build up dangerous levels of these peroxides in months, whereas samples of MTBE are usually safe for years.
Storage
As MTBE doesn't form explosive organic peroxides, no special storage is required. Bottles containing MTBE should be kept in a cold place, away from any heat or fire source.
Disposal
MTBE can be safely burned. However, it must never dumped in the environment.
