Description

n-Butane is a highly versatile, straight-chain alkane hydrocarbon that serves as a fundamental building block and energy source across numerous industrial sectors. Its high volatility and gaseous state under standard conditions make it an efficient and clean-burning fuel component and a critical feedstock for chemical synthesis. This product is essential for manufacturers in the petrochemical, energy, and specialty chemical industries, where it is used to produce ethylene and butadiene, as a propellant in aerosol formulations, and as a fuel for lighters, torches, and heating.

Application

• Petrochemical Feedstock: A primary raw material for steam cracking to produce ethylene and for catalytic dehydrogenation to manufacture 1,3-butadiene, a key monomer for synthetic rubber (e.g., SBR, polybutadiene).
• Fuel & Energy Source: Blended with propane to create Liquefied Petroleum Gas (LPG) for heating, cooking, and transportation fuel. Also used as a fuel in portable lighters, torches, and camping stoves.
• Aerosol Propellant: Utilized as a propellant in various aerosol products, including personal care items (hairsprays, deodorants), household cleaners, and industrial sprays, valued for its clean combustion profile.
• Refrigerant: Serves as a component in refrigerant blends, particularly in systems designed for hydrocarbons, due to its favorable thermodynamic properties.
• Chemical Synthesis: Used as a feedstock in alkylation processes to produce high-octane gasoline components and in the production of maleic anhydride and other specialty chemicals.
• Calibration Standard: Employed as a reference standard in gas chromatography and other analytical instrumentation within quality control and research laboratories.

Quality Control

Our n-Butane is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity, hydrocarbon composition, and impurity levels (e.g., sulfur compounds, water content). Our quality systems are designed to meet the rigorous demands of industrial and specialty gas applications, ensuring product integrity from our facility to your point of use.

Storage

Store in a cool, well-ventilated area away from direct sunlight, heat sources, and ignition points. Containers must be kept tightly closed and clearly labeled. Due to its highly volatile and gaseous nature, n-Butane must be stored in approved pressure vessels (cylinders or bulk tanks) designed for liquefied petroleum gas. Storage areas should comply with all local and national regulations for flammable gases.
