Diethyl Ether is a colorless, highly volatile organic liquid with a characteristic sweet odor. It is widely used as a solvent in chemical reactions, extractions, and historically as a general anesthetic. Known for its low boiling point and good miscibility with many organic solvents.
🏭⚗️ Production
Diethyl ether is industrially produced primarily by the acid-catalyzed dehydration of ethanol using sulfuric acid under controlled temperature conditions. Another production method involves the catalytic hydration of ethylene. The product is purified through distillation to remove impurities.
🔬 Properties
Diethyl ether has the chemical formula C₄H₁₀O and a molar mass of approximately 74.12 g/mol. It is a colorless, highly volatile liquid with a sweet, ether-like odor. Ether is slightly soluble in water but miscible with most organic solvents. It has a low boiling point (~34.6 °C), high vapor pressure, and is highly flammable. Prolonged exposure to air and light can lead to the formation of explosive peroxides.
🧪 Applications
Diethyl ether is widely used as a solvent in organic synthesis, particularly in Grignard reactions and liquid-liquid extractions. It has historical use as a general anesthetic. It is also employed in the manufacturing of pharmaceuticals and plastics.
⚠️ Safety
Diethyl ether is highly flammable and its vapors can form explosive mixtures with air. Exposure to high concentrations may cause dizziness, respiratory irritation, and central nervous system effects. It should be handled with proper ventilation, kept away from ignition sources, and stored in tightly sealed containers in a cool, dark place.
