Ethoxyethane

Ethoxyethane is an organic chemical compound with the molecular formula C4H10O and CAS number 60-29-7. Also commonly known as diethyl ether, it has a molecular weight of 74.12 g/mol and belongs to the ether family of compounds. This substance is classified as a highly flammable liquid with acute toxicity properties and specific target organ toxicity. It carries the danger signal word and requires careful handling due to its hazardous nature.

Ethoxyethane is a colorless, volatile liquid with a characteristic sweet, pungent odor at room temperature. It has excellent solvent properties and is highly volatile, making it easily evaporable. The compound is relatively lightweight with its molecular mass of 74.12 g/mol and has low boiling point characteristics typical of ethers. Its chemical structure consists of two ethyl groups connected by an oxygen atom, giving it distinctive ether properties including high flammability and low flash point.

Ethoxyethane serves primarily as a laboratory solvent and extraction agent in chemical processes. It is widely used in pharmaceutical manufacturing, organic synthesis, and analytical chemistry applications. The compound acts as an excellent solvent for fats, oils, waxes, and various organic compounds. In industrial settings, it functions as a reaction medium and extraction solvent. Its volatility and solvent properties make it valuable in chromatography and purification processes, though its use requires strict safety protocols.

Ethoxyethane requires strict safety protocols including use of appropriate personal protective equipment such as chemical-resistant gloves, safety goggles, and respiratory protection when necessary. Work must be conducted in well-ventilated areas or under fume hoods to prevent vapor accumulation. Eliminate all ignition sources as the substance is extremely flammable (Class 1 flammable liquid). Use grounded equipment to prevent static electricity buildup and ensure emergency procedures are readily available for spill management and exposure incidents.

Ethoxyethane must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames due to its Class 1 flammable liquid classification. Use appropriate flame-resistant storage cabinets and ensure containers are tightly sealed to prevent vapor escape. Store away from oxidizing agents and incompatible materials. Maintain storage temperatures below recommended limits and implement proper inventory rotation. Ground all storage containers and transfer equipment to prevent static electricity accumulation during handling operations.

Ethoxyethane exposure requires immediate action depending on the contact route. For skin contact, remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately and seek medical attention if breathing difficulties occur. For ingestion, do not induce vomiting and seek immediate medical assistance while providing safety data sheet information to medical personnel.

Ethoxyethane disposal must comply with local and European waste regulations as hazardous chemical waste. The substance cannot be disposed of through regular waste streams due to its flammable and toxic properties. Contact licensed hazardous waste disposal companies for proper collection and treatment. Ensure containers are properly labeled and segregated from other waste types. Recovery or recycling may be possible through specialized facilities, but incineration at authorized high-temperature facilities is typically the preferred disposal method for contaminated materials.

Ethoxyethane is classified under ADR Class 3 (flammable liquids), Packing Group I, indicating high danger level for transport. Shipments require proper dangerous goods packaging, labeling with appropriate hazard symbols, and transport documentation including safety data sheets. Vehicles must comply with ADR regulations including equipment requirements and route restrictions. Only trained personnel should handle transportation, and emergency response information must accompany shipments. Special precautions against static electricity and ignition sources are mandatory during loading and unloading operations.

Ethoxyethane is regulated under European REACH and CLP regulations requiring registration and classification as Flam. Liq. 1; Acute Tox. 4; STOT SE 3 with danger signal word and GHS02, GHS07 pictograms. While not currently listed as a Substance of Very High Concern (SVHC), it requires safety data sheets and proper hazard communication. National regulations may impose additional restrictions on storage quantities, workplace exposure limits, and handling requirements. Users must ensure compliance with occupational safety regulations and environmental protection requirements in their respective countries.

Ethoxyethane is available through OYSI, a European distributor specializing in technical chemical products. As an established chemical supplier, OYSI can provide ethoxyethane with proper documentation including safety data sheets, certificates of analysis, and regulatory compliance information. Professional customers can contact OYSI for availability, specifications, and delivery options across European markets. Due to the substance's hazardous classification, purchases typically require demonstration of legitimate professional use and compliance with applicable safety and storage requirements.
