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, featuring a methyl group attached to the second carbon of a four-carbon chain. This colorless, highly flammable liquid has a molecular weight of 72.15 g/mol and belongs to the family of saturated hydrocarbons, making it a volatile organic compound commonly used in industrial applications.

2-methylbutane is a colorless liquid with a characteristic gasoline-like odor at room temperature. It has a low boiling point and high volatility, making it readily evaporable. The compound is practically insoluble in water but highly soluble in organic solvents like alcohols and ethers. Its branched structure gives it different physical properties compared to its straight-chain isomer n-pentane, including slightly lower boiling point and different octane rating characteristics.

2-methylbutane is primarily used as a component in gasoline blends due to its favorable octane properties. It serves as a solvent in various industrial processes and as a raw material in petrochemical synthesis. The compound is also utilized in the production of other chemicals through cracking and reforming processes. Additionally, it finds applications in laboratory settings as an extraction solvent and in calibration standards for analytical instruments.

2-methylbutane requires careful handling due to its extreme flammability and health hazards. Use appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and flame-resistant clothing. Work in well-ventilated areas or under fume hoods to prevent vapor accumulation. Eliminate all ignition sources including static electricity, open flames, and hot surfaces. Ground all equipment to prevent static discharge and use explosion-proof electrical equipment when working with this substance.

2-methylbutane must be stored in tightly sealed containers in cool, dry, well-ventilated areas away from heat sources and ignition points. Use appropriate storage containers designed for flammable liquids and ensure proper grounding to prevent static electricity buildup. Keep away from oxidizing agents and strong acids. Storage areas should be equipped with appropriate fire suppression systems and maintained below recommended temperature limits to minimize vapor formation and explosion risks.

In case of skin contact with 2-methylbutane, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water. For eye contact, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air immediately and monitor for respiratory distress. In case of ingestion, do not induce vomiting due to aspiration toxicity risks and seek immediate medical attention.

2-methylbutane must be disposed of as hazardous waste according to local and national environmental regulations. Never pour it down drains, toilets, or onto soil as it poses environmental risks to aquatic systems. Contact licensed hazardous waste disposal companies for proper collection and treatment. Small quantities can be disposed of through solvent recovery programs or incineration at appropriate high-temperature facilities equipped with pollution control systems to prevent environmental contamination.

2-methylbutane is classified as ADR Class 3 (flammable liquid) Packing Group I, indicating high danger level for transport. It requires appropriate UN-specification packaging and proper labeling with flammable liquid hazard labels. Transport vehicles must be equipped with appropriate safety equipment and drivers must have ADR certification. Shipping documents must include proper shipping names, hazard classes, and emergency contact information. Follow all applicable transport regulations for dangerous goods.

2-methylbutane is subject to various European chemical regulations including CLP (Classification, Labelling and Packaging) and REACH registration requirements. It is not classified as a Substance of Very High Concern (SVHC) but requires appropriate hazard communication through safety data sheets and product labeling. Workplace exposure limits may apply, and users must comply with environmental discharge regulations due to its aquatic toxicity classification and flammability restrictions.
