High-purity boron trifluoride (BF₃) gas supplied from China for organic synthesis, catalysis, and industrial processing.
High-purity boron trifluoride (BF₃) gas for esterification, alkylation, polymerization, and petroleum refining.
Boron trifluoride is a colorless gas with a sharp, pungent, and persistent acidic odor. As a strong Lewis acid, it readily hydrolyzes in moist air to form dense white fumes and rapidly dissolves in water and organic compounds containing nitrogen or oxygen. Boron trifluoride serves as an efficient catalyst in various organic reactions, including esterification, alkylation, polymerization, isomerization, sulfonation, and nitration. It is also used as an antioxidant during magnesium casting and alloying, and is a key raw material for producing boron halides, elemental boron, boranes, and sodium borohydride. Additionally, it acts as a catalyst in petroleum refining and condensation reactions, typically transported as a liquefied compressed gas.
Global Shipping & Export Compliance
Boron trifluoride (UN 1008) is classified as a toxic and corrosive 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
