CAS Number: 60-29-7
Appearance: Colorless, volatile liquid with a characteristic sweet odor

Diethyl ether is a highly flammable, low-boiling-point organic solvent widely used in laboratories and industrial applications. It exhibits excellent solvent properties for a wide range of non-polar and moderately polar compounds. Due to its volatility and low flash point, it requires careful handling and storage.

Chemical and Physical Properties

• Density: ~0.713 g/cm³ at 20 °C

• Boiling Point: 34.6 °C

• Solubility in Water: Slightly soluble (6.05 g/100 mL at 25 °C)

• Miscibility: Miscible with alcohols, chloroform, acetone, and other organic solvents

• Vapor Pressure: 440 mmHg at 20 °C

• Flash Point: −45 °C (closed cup)

• Autoignition Temperature: ~160 °C

• Explosive Limits: 1.9% (LEL) – 48.0% (UEL)

Applications

Laboratory Solvent

• Commonly used for extraction, recrystallization, and sample preparation of non-polar or slightly polar compounds.

Chemical Synthesis

• Acts as a reaction medium in organic chemistry and in the preparation of compounds including organometallic reagents.

Fuel Additive

• Utilized in engine starting fluids due to its volatility and ease of ignition.

Industrial Cleaning

• Applied in some industrial degreasing processes where rapid solvent evaporation is desired.

First Aid Measures

Inhalation: Move person to fresh air. If breathing is difficult, administer oxygen. Seek medical attention.
Skin Contact: Remove contaminated clothing. Rinse skin with water. If irritation occurs, seek medical advice.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Seek medical attention.
Ingestion: Rinse mouth. Do not induce vomiting. Seek immediate medical assistance.

Handling and Storage

• Storage Conditions: Store in a cool, dry, and well-ventilated area. Keep containers tightly closed and protected from light.

• Handling Precautions: Avoid static discharge. Use spark-free tools and explosion-proof equipment. Monitor for peroxide formation, especially after prolonged storage.

• Compatibility: Incompatible with oxidizing agents, acids, and peroxides.

Environmental Considerations

Diethyl ether is volatile and may contribute to ground-level ozone formation. Prevent spills from entering waterways or soil. Waste should be handled as hazardous and disposed of according to environmental regulations.
