n-Pentane

N-pentane is a clear, colorless liquid with a petroleum-like odor. It is a straight-chain alkane with the chemical formula C5H12. It is the simplest pentane isomer, and is also known as normal pentane or undecane.

N-pentane is a volatile organic compound (VOC) and a flammable liquid. It has a flash point of -57°F and a boiling point of 97°F. It is less dense than water and insoluble in water, but it is miscible with most organic solvents.

N-pentane is a major component of gasoline and is also used as a solvent, a refrigerant, and a propellant. It is also used in the production of other chemicals, such as adipic acid and nylon.

Here are some of the properties of n-pentane:

• Molecular formula: C5H12
• Molar mass: 72.15 g/mol
• Melting point: -129.8°C
• Boiling point: 97°C
• Flash point: -57°F
• Density: 0.626 g/cm3 (at 20°C)
• Vapor pressure: 426 mmHg (at 20°C)
• Solubility in water: 0.004 g/L (at 20°C)
• Miscible with most organic solvents
• Flammable
• Toxic to aquatic organisms

N-pentane is a hazardous substance and should be handled with care. It can be harmful if inhaled, ingested, or absorbed through the skin. It can also cause fire or explosion if not stored properly.

If you are working with n-pentane, it is important to wear personal protective equipment (PPE) such as gloves, goggles, and a respirator. You should also store n-pentane in a cool, well-ventilated area away from heat and flames.
