High-purity n-butane (n-C₄H₁₀) gas supplied from China for fuel blending, refrigeration, and chemical synthesis.
High-purity n-butane (n-C₄H₁₀) for solvent applications, refrigerant systems, organic synthesis, and LPG fuel blending.
N-Butane is a colorless gas with a slightly unpleasant odor. As a straight-chain alkane, it is insoluble in water but soluble in alcohol and chloroform. It is highly flammable and explosive, forming flammable mixtures with air. N-Butane serves as a versatile industrial gas, used as a solvent, refrigerant, and raw material for synthetic organic materials. It is also a key component in LPG fuel blending and an intermediate in various chemical processes. The gas is typically transported as a liquefied compressed gas under pressure.
Global Shipping & Export Compliance
N-Butane (UN 1011) is classified as a flammable compressed gas and must be handled under strict hazardous materials regulations.
- Sea freight (FCL / LCL) – standard export method
- Air freight – limited availability (regulatory controlled)
Required Export Documents
- Material Safety Data Sheet (MSDS)
- Certificate of Analysis (COA)
- Dangerous Goods Declaration (DGD)
- UN-certified cylinder documentation
- Commercial invoice & packing list
How to Order N-Butane Gas from China
- Send technical requirements (purity, cylinder specification, application)
- Receive quotation (EXW / FOB / CIF options)
- Confirm cylinder specification & compliance
- Review COA, MSDS, and certification documents
- Production, filling, and quality inspection
- Hazardous goods shipping arrangement
- Delivery and final inspection at destination
Common Mistakes When Buying N-Butane Gas
- Choosing suppliers only based on lowest price
- Ignoring cylinder certification and pressure rating
- Not verifying moisture and impurity levels
- Skipping third-party inspection before shipment
- Overlooking export documentation compliance
