2-ethyloxirane

2-ethyloxirane is an organic chemical compound with the molecular formula C4H8O and CAS number 106-88-7. It belongs to the epoxide family, characterized by a three-membered ring containing an oxygen atom. With a molecular weight of 72.11 g/mol, this substance is classified as a flammable liquid with significant health hazards including carcinogenic potential and acute toxicity. It requires careful handling due to its dangerous properties.

2-ethyloxirane is a colorless liquid at room temperature with a characteristic ether-like odor. As an epoxide with molecular formula C4H8O, it exhibits high reactivity due to the strained three-membered ring structure. The compound has moderate volatility and is miscible with most organic solvents. Its epoxide functionality makes it prone to ring-opening reactions, particularly in the presence of acids, bases, or nucleophiles.

2-ethyloxirane is primarily used as an intermediate in chemical synthesis and as a reactive diluent in epoxy resin formulations. Its epoxide functionality makes it valuable for producing specialty chemicals, surfactants, and polymer additives. The compound serves in the manufacture of glycol ethers, plasticizers, and other industrial chemicals. Due to its carcinogenic classification, its use is restricted to professional industrial applications with appropriate safety measures.

2-ethyloxirane requires strict safety protocols due to its flammable, carcinogenic, and toxic properties. Personnel must wear full chemical-resistant suits, respiratory protection, and safety goggles. Work should be conducted in well-ventilated areas away from ignition sources. Avoid skin and eye contact, and prevent vapor inhalation. Emergency shower and eyewash stations must be readily accessible. Only trained professionals should handle this substance following established safety procedures.

2-ethyloxirane must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Use tightly sealed, chemically compatible containers in a dedicated chemical storage facility. Keep away from acids, bases, and oxidizing agents that could trigger dangerous reactions. Storage areas should have appropriate fire suppression systems and spill containment measures. Temperature should be controlled to prevent excessive vapor generation.

Immediate action is required upon contact with 2-ethyloxirane. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15 minutes. If inhaled, move person to fresh air immediately. For ingestion, do not induce vomiting. Seek immediate medical attention in all cases and provide the safety data sheet to medical personnel.

2-ethyloxirane disposal must comply with local and national hazardous waste regulations due to its carcinogenic and toxic properties. The substance cannot be disposed of in regular waste streams and requires specialized hazardous waste treatment. Contact licensed waste disposal companies for proper collection and destruction, typically through high-temperature incineration. Never discharge into drains, soil, or water bodies. Maintain detailed disposal records as required by environmental regulations.

2-ethyloxirane is classified under ADR Class 3 (flammable liquids), Packing Group II, indicating moderate danger level. Transportation requires compliant packaging, proper labeling with GHS pictograms (GHS02, GHS08, GHS07), and appropriate documentation. Vehicles must be equipped with fire extinguishers and emergency equipment. Drivers need hazardous materials training and certification. Transport should avoid extreme temperatures and ensure proper ventilation to prevent vapor accumulation.

2-ethyloxirane is subject to extensive European regulations including REACH registration, CLP classification requirements, and workplace exposure limits. Its Carcinogenic Category 2 classification triggers specific occupational health regulations and labeling requirements. The substance requires safety data sheets and proper hazard communication. Industrial users must implement risk management measures and may need authorization for certain uses. Regular monitoring and reporting may be mandatory depending on usage quantities and applications.
