CH3CH2OCH3

CH3CH2OCH3, also known as ethyl methyl ether, is an organic compound with the chemical formula C3H8O. It is a simple ether, characterized by an oxygen atom bonded to an ethyl group (CH3CH2-) and a methyl group (CH3-). At room temperature and pressure, ethyl methyl ether is a colorless liquid. It possesses a distinctive odor.

This compound is typically synthesized through the Williamson ether synthesis, where a sodium ethoxide solution reacts with methyl halide, or alternatively, sodium methoxide reacts with ethyl halide. Another method involves the dehydration of a mixture of ethanol and methanol under acidic conditions. Ethyl methyl ether is flammable and should be handled with appropriate precautions. Its solubility in water is limited, but it is miscible with many organic solvents.

Ethyl methyl ether finds limited applications in industrial settings. It has been explored as a potential fuel additive due to its relatively high octane rating. However, its volatility and flammability present challenges for widespread use. It can also be used as a solvent in some laboratory procedures. Its presence in the environment is generally low, and it is not considered a significant pollutant.
