2-methylbutane

2-methylbutane is a branched-chain alkane hydrocarbon with the molecular formula C5H12 and CAS number 78-78-4. It is an isomer of pentane, characterized by a methyl group attached to the second carbon of a four-carbon chain. With a molecular weight of 72.15 g/mol, this volatile organic compound is classified as a highly flammable liquid and poses significant safety risks including aspiration toxicity and narcotic effects at high concentrations.

2-methylbutane is a colorless liquid at room temperature with a characteristic gasoline-like odor. It has a relatively low boiling point and high volatility, making it readily evaporable. The compound is practically insoluble in water but miscible with most organic solvents. Its branched structure gives it different physical properties compared to its linear isomer n-pentane, including slightly different boiling and melting points, while maintaining similar density and flammability characteristics.

2-methylbutane is primarily used as a component in gasoline blending due to its high octane rating and favorable combustion properties. It serves as a solvent in various industrial processes and chemical syntheses. The compound is also utilized in the production of other chemicals through cracking and reforming processes in petrochemical industries. Additionally, it can be used as a reference standard in analytical chemistry and as a blowing agent in some specialized applications.

2-methylbutane requires strict safety measures due to its extreme flammability and health hazards. Personnel must wear appropriate PPE including chemical-resistant gloves, safety goggles, and respiratory protection in poorly ventilated areas. All ignition sources must be eliminated, and only explosion-proof electrical equipment should be used. Work areas must be well-ventilated, and static electricity buildup should be prevented through proper grounding. Emergency procedures and spill response materials must be readily available.

2-methylbutane must be stored in cool, well-ventilated areas away from heat sources, sparks, and open flames. Storage containers should be made of compatible materials and kept tightly sealed to prevent vapor release. The storage area must be equipped with explosion-proof electrical equipment and proper fire suppression systems. Keep away from oxidizing agents and other incompatible materials. Regular inspection of containers for leaks is essential, and storage should comply with local flammable liquid regulations.

Skin contact with 2-methylbutane requires immediate removal of contaminated clothing and washing the affected area with soap and water. For eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air immediately and monitor for respiratory difficulties. In case of ingestion, do not induce vomiting due to aspiration hazard - seek immediate medical attention. Remove all ignition sources and ensure proper ventilation in the contaminated area.

2-methylbutane disposal must comply with local and European waste regulations as it is classified as hazardous waste. The substance should never be poured down drains or released into the environment due to its aquatic toxicity. Disposal should be handled by licensed waste management companies through appropriate methods such as incineration in specialized facilities. Empty containers may still contain hazardous residues and require proper cleaning or disposal. Consult local authorities for specific disposal requirements and approved facilities.

2-methylbutane is classified as ADR Class 3 (flammable liquids), Packing Group I, indicating high danger during transport. Transportation requires UN-specification packaging and proper hazard labeling with appropriate placards. Vehicles must comply with ADR requirements including electrical equipment specifications and emergency equipment. Transport documents must include proper shipping names, hazard classes, and emergency response information. Only trained personnel should handle transportation, and routes should avoid populated areas where possible.

2-methylbutane is subject to various European regulations including CLP (Classification, Labelling and Packaging) requiring specific hazard pictogrammes (GHS02, GHS07, GHS08, GHS09) and danger signal word. It falls under REACH regulation for chemical registration and evaluation, though it is not currently listed as a SVHC (Substance of Very High Concern). Users must comply with occupational safety regulations, environmental protection laws, and transport regulations (ADR). Industrial emissions may be subject to additional environmental permits and monitoring requirements.
