2metyylibutaania

2-Methylbutane, also known as isopentane, is a branched-chain alkane with the chemical formula C5H12. It is an isomer of pentane, meaning it has the same chemical formula but a different structural arrangement of atoms. In 2-methylbutane, a methyl group (CH3) is attached to the second carbon atom of a butane chain.

This colorless, volatile liquid has a characteristic gasoline-like odor. It is highly flammable and has a low boiling point of approximately 27.8 degrees Celsius (82.0 degrees Fahrenheit), causing it to readily evaporate at room temperature. 2-Methylbutane is a component of natural gas and petroleum.

Industrially, 2-methylbutane is produced through the isomerization of n-pentane. It is primarily used as a component in gasoline to increase its octane rating, which enhances engine performance and reduces knocking. It also finds applications as a blowing agent in the production of expandable polystyrene and as a solvent in various chemical processes.

Due to its high flammability, 2-methylbutane must be handled with care and stored in well-ventilated areas away from ignition sources. Its low flash point and wide flammability limits make it a potential fire hazard.
