But-1-ene

But-1-ene is an alkene hydrocarbon with the molecular formula C4H8 and CAS number 106-98-9. It is a linear four-carbon chain with a double bond at the terminal position, making it the simplest butene isomer. With a molecular weight of 56.11 g/mol, but-1-ene is an important petrochemical intermediate used in various industrial processes and polymer production.

But-1-ene is a colorless gas at room temperature with a characteristic sweet odor typical of alkenes. It has a boiling point of -6.3°C and melting point of -185.3°C. The compound is highly flammable and poorly soluble in water but readily soluble in organic solvents. Its density as a liquid is approximately 0.595 g/cm³ at 20°C.

But-1-ene serves as a key building block in petrochemical industry for producing various chemicals and polymers. It is primarily used as a comonomer in polyethylene production to improve film properties and flexibility. Additionally, it acts as an intermediate in manufacturing butylene oxide, synthetic lubricants, and plasticizers. The compound is also utilized in organic synthesis reactions.

But-1-ene requires careful handling due to its flammable nature and gaseous state. Use appropriate personal protective equipment including safety glasses, protective gloves, and ensure adequate ventilation. Eliminate all ignition sources and use explosion-proof equipment. Handle in well-ventilated areas or fume hoods, avoid breathing vapors, and use proper gas handling techniques including pressure regulators and leak detection methods.

But-1-ene should be stored in appropriate pressure vessels designed for compressed gases in cool, dry, well-ventilated areas away from heat sources and ignition. Keep containers upright and secured, away from incompatible materials such as strong oxidizers. Storage areas must be equipped with gas detection systems and emergency ventilation. Maintain temperatures below 40°C and protect from direct sunlight.

But-1-ene exposure requires immediate action depending on the route of contact. For inhalation, move to fresh air immediately and seek medical attention if breathing difficulties occur. In case of skin contact during handling of cold liquid, treat as frostbite with lukewarm water. For eye contact, flush with water for 15 minutes. Always consult safety data sheets and seek medical advice when necessary.

But-1-ene disposal must comply with local and national waste regulations as it is classified as hazardous waste. Do not release into atmosphere or sewerage systems. Contact licensed waste disposal companies specializing in chemical waste management. Small quantities can be carefully vented in well-ventilated areas if permitted by regulations. Always consult local environmental authorities for specific disposal requirements.

But-1-ene is classified under ADR Class 2 as a compressed gas, requiring specialized transport conditions. Use appropriate pressure vessels and packaging designed for compressed gases. Vehicles must comply with ADR regulations including proper labeling, documentation, and emergency equipment. Transport should be conducted by trained personnel with appropriate certifications for dangerous goods handling and compressed gas transport.

But-1-ene is subject to various European regulations including REACH registration requirements and CLP classification standards. It is not listed as a Substance of Very High Concern (SVHC) under REACH. Companies must comply with industrial emissions regulations and workplace safety standards. Transport is regulated under ADR for dangerous goods, and users must follow national chemical safety legislation.

But-1-ene is available through specialized chemical distributors across Europe, including OYSI, a professional European distributor of industrial chemicals. When sourcing but-1-ene, ensure suppliers provide proper documentation, safety data sheets, and comply with REACH regulations. Consider factors such as purity grades, packaging options, delivery logistics for compressed gases, and technical support for your specific application requirements.
