Diethyl ether, also known as ethoxyethane or simply ether, is a commonly used organic solvent with various industrial and laboratory applications. Here is an overview of the physical and chemical properties of diethyl ether as outlined in diethyl ether sds:

1. Physical Properties:

   • Appearance: Diethyl ether is a colorless, volatile liquid with a characteristic sweet, ether-like odor.
   • Molecular Formula: C4H10O
   • Molecular Weight: 74.12 g/mol
   • Boiling Point: Diethyl ether has a relatively low boiling point of approximately 34.6°C (94.3°F), making it highly volatile.
   • Melting Point: It has a melting point of -116.3°C (-177.3°F).
   • Density: The density of diethyl ether is approximately 0.713 g/cm³ at 20°C (68°F).
   • Solubility: Diethyl ether is miscible with a wide range of organic solvents and is moderately soluble in water.

2. Chemical Properties:

   • Flammability: Diethyl ether is highly flammable and can form explosive vapors when exposed to an ignition source. It has a flashpoint of -45°C (-49°F) and an autoignition temperature of 160°C (320°F).
   • Reactivity: Diethyl ether is relatively stable under normal conditions. However, it can form explosive peroxides upon prolonged exposure to air and light or when stored for extended periods. Precautions should be taken to prevent the accumulation of peroxides.
   • Miscibility: Diethyl ether is miscible with a wide range of organic solvents, making it useful in various extraction and purification processes.
   • Chemical Reactivity: Diethyl ether is relatively unreactive toward many common chemicals. However, it can react with strong oxidizing agents and undergo peroxidation reactions when exposed to air.

3. Health and Safety Considerations:

   • Inhalation: Inhalation of diethyl ether vapors can cause dizziness, drowsiness, and respiratory irritation. Prolonged or excessive exposure may lead to narcotic effects and even unconsciousness.
   • Skin and Eye Contact: Contact with diethyl ether can cause irritation, redness, and drying of the skin. It may also cause severe eye irritation or damage upon direct contact.
   • Ingestion: Ingestion of diethyl ether can cause gastrointestinal irritation, nausea, vomiting, and central nervous system depression.
   • Environmental Impact: Diethyl ether is volatile and can contribute to air pollution. It should be handled and disposed of properly to prevent environmental contamination.

It is crucial to follow proper handling procedures, ventilation requirements, and personal protective measures when working with diethyl ether to minimize potential health and safety risks.
