Description

Tetrabutylphosphonium 2H,2H-Perfluorodecanoate is a high-performance ionic liquid and phase-transfer catalyst combining a phosphonium cation with a fluorinated carboxylate anion. This unique structure provides exceptional thermal stability, low miscibility with water, and high solubility in both organic and fluorinated solvents, making it a valuable specialty chemical for demanding processes. It is primarily sought by R&D and production teams in the pharmaceutical, advanced materials, and specialty chemical synthesis sectors for applications requiring robust, non-nucleophilic bases or catalysts in harsh environments.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly in fluorinated systems or for the synthesis of specialty polymers and fine chemicals.
• Ionic Liquid Solvent/Medium: Serves as a green, non-volatile reaction medium for high-temperature organic synthesis, electrochemical applications, and separations.
• Surfactant/Emulsifier for Fluorinated Systems: Used in the formulation of fluorosurfactants, coatings, and fire-fighting foams where fluorocarbon compatibility is critical.
• Stabilizer and Additive: Acts as a thermal and chemical stabilizer in advanced lubricants, greases, and high-performance polymer composites.
• Nucleophilic Catalyst: Employed in esterification, transesterification, and other condensation reactions where a strong, non-coordinating base is required.
• Electrolyte Component: Investigated for use in lithium-ion batteries and other electrochemical devices due to its wide electrochemical window and stability.

Quality Control

Our Tetrabutylphosphonium 2H,2H-Perfluorodecanoate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
