n-Butane (C4H10) Gas
n-Butane (C4H10) is a colorless, flammable, liquefied gas.
n-Butane
Formula: C4H10
CAS No: 106-97-8
n-Butane (C4H10) is a colorless, highly flammable hydrocarbon gas commonly supplied as a liquefied gas under moderate pressure. It is widely used as a fuel, propellant, and petrochemical feedstock due to its clean-burning properties and ease of liquefaction.
In industrial applications, n-butane serves as a key component in liquefied petroleum gas (LPG), gasoline blending, and chemical manufacturing. It is also used as a propellant and solvent, where controlled vaporization and consistent performance are required across a range of commercial and specialty applications.
Applications Include:
- Used as a fuel component in LPG, portable heating, cooking, and energy applications.
- Blended into gasoline to control vapor pressure and improve fuel performance.
- Serves as a petrochemical feedstock for the production of ethylene, butadiene, and other intermediates.
- Used as an aerosol propellant and in lighter fuels due to its controlled vaporization.
- Applied as a solvent and extraction medium in industrial and specialty processes.
EFC Gases & Advanced Materials supplies high-purity n-butane with tight control of moisture and critical impurities, supported by rigorous analytical verification to ensure consistent performance in demanding applications.
