Et2O
Diethyl ether, also known as ethoxyethane, is an organic solvent with the chemical formula C4H10O and a molar mass of 74.12 g/mol. It is a colorless, highly volatile liquid with a characteristic sweet odor. It is the simplest dialkyl ether and was historically the most widely used general anesthetic.
Diethyl ether has a boiling point of 34.6°C and is miscible with many organic solvents; it is
Industrially produced by acid-catalyzed dehydration of ethanol using sulfuric acid or similar catalysts. It is stored
Applications: as a versatile solvent in organic synthesis, particularly for moisture-sensitive reagents such as Grignard reagents
Safety: highly flammable; flash point around -45°C; vapors can form explosive mixtures with air; inhalation may
