CAS 637-92-3: Ethyl tert-butyl ether

Description: Ethyl tert-butyl ether (ETBE) is an organic compound classified as an ether, with the chemical formula C6H14O. It is characterized by its clear, colorless liquid form and has a distinctive, pleasant odor. ETBE is known for its low boiling point and moderate solubility in water, making it useful as a solvent and fuel additive. It is primarily utilized in the production of gasoline as an oxygenate to enhance octane ratings and reduce emissions. ETBE is less toxic than other ethers, such as diethyl ether, and exhibits a relatively low volatility, which contributes to its stability in various applications. The compound is produced through the reaction of ethanol and isobutylene, and it is valued for its ability to improve combustion efficiency in engines. However, like many organic compounds, it should be handled with care due to potential health effects upon exposure. Overall, ETBE is an important chemical in the context of fuel formulation and environmental considerations.
