Industrial & High Purity Grade Boron Trifluoride-Phenol ComplexCAS 462-05-5 Lewis Acid Catalyst for Phenolic Resin Synthesis & Organic Reactions

Boron Trifluoride-Phenol Complex (1:2) (CAS:462-05-5,EINECS:207-321-2, HS Code:2812900000) is a red-brown to dark-brown clear liquid with characteristic phenol odor. It is a highly efficient Lewis acid catalyst with a BF₃ content of 25-30%. This complex is soluble in ethers, alcohols and common organic solvents, while insoluble in water. It is widely used in organic synthesis, phenolic resin production, and various chemical reactions requiring strong acid catalysis.

Applications
Phenolic Resin Industry (Core Application)
Acts as premium catalyst for synthesizing high-performance phenolic resins, including resol and novolac types. It accelerates polymerization, improves resin cross-linking density, and enhances thermal stability, mechanical strength and adhesion of final products, widely used in molding compounds, adhesives and composite materials.
Organic Synthesis Reactions
Powerful Lewis acid catalyst for esterification, etherification, alkylation, isomerization and condensation reactions. Particularly effective in Friedel-Crafts reactions, Beckmann rearrangement, and conversion of oximes to amides.
Polymer Modification
Used for improving thermal and mechanical properties of epoxy resins, polyurethanes and other polymers. It enhances cross-linking efficiency, increases glass transition temperature and improves chemical resistance of polymer materials.
Pharmaceutical & Fine Chemicals
Key catalyst for synthesizing pharmaceutical intermediates, specialty chemicals and agrochemicals. It enables high-yield production of complex organic molecules with high selectivity and purity.
Petrochemical Industry
Applied in hydrocarbon cracking, isomerization of alkanes and olefins, and purification processes. It helps increase product yield and improve product quality in refinery operations.
