Description

Fluoroantimonic Acid is a superacid of immense chemical strength, recognized as one of the strongest proton donors known. This extreme acidity makes it a uniquely powerful catalyst and reagent for demanding chemical transformations where conventional acids are ineffective. It is a critical material for advanced research and industrial processes in petrochemical alkylation, specialty chemical synthesis, and the study of stable carbocations.

Application

• Superacid Catalyst: Used in petrochemical refining for the alkylation of isobutane with olefins to produce high-octane gasoline components.
• Organic Synthesis: Facilitates challenging reactions like isomerization, acylation, and nitration under mild conditions.
• Carbocation Generation & Stabilization: Essential in fundamental research for generating and studying long-lived carbocation intermediates in solution.
• Inorganic & Organometallic Chemistry: Acts as a potent fluorinating and protonating agent for metal complexes and inorganic substrates.
• Polymerization Initiator: Employed in cationic polymerization processes for specific monomers.
• Analytical Chemistry: Used as an extreme-condition reagent in specialized analytical methodologies.

Quality Control

Our Fluoroantimonic Acid is manufactured and handled under stringent controls to ensure batch-to-batch consistency and high chemical performance. Quality is verified through advanced analytical techniques including titration and spectroscopic methods. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and key parameters is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its nature as a strong acid/organic solvent mixture and highly volatile properties, store in a cool, well-ventilated area, away from moisture, heat, and incompatible materials such as bases and organic compounds. Use appropriate corrosion-resistant secondary containment.
