Description

Trihexyl(Tetradecyl)Phosphonium Bis(Trifluoromethylsulfonyl)Imide is a high-performance ionic liquid, specifically a phosphonium-based cation paired with a hydrophobic, weakly coordinating anion. This compound matters for its exceptional thermal stability, low volatility, and high ionic conductivity, making it a superior alternative to traditional solvents and electrolytes. It is critically needed by industries focused on advanced energy storage, high-temperature catalysis, and specialized chemical synthesis where robust, non-aqueous media are required.

Application

• Electrolyte Component for Lithium-Ion Batteries: Used as an additive or co-solvent to enhance thermal stability, safety, and cycle life of high-voltage battery systems.
• High-Temperature Reaction Medium: Serves as a stable, non-volatile solvent for organic synthesis, polymerization, and catalysis under demanding thermal conditions.
• Gas Separation & Capture: Employed in supported ionic liquid membranes (SILMs) for the selective separation of CO2 and other acidic gases from industrial streams.
• Lubricant & Additive: Functions as a high-performance lubricant or anti-wear additive for extreme-pressure and high-temperature mechanical applications.
• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly in pharmaceutical and fine chemical manufacturing.
• Antistatic Agent: Incorporated into polymers and coatings to provide durable electrostatic discharge (ESD) protection.
• Analytical Chemistry: Utilized as a stationary phase modifier in gas chromatography (GC) and other separation techniques.
• Electroplating Baths: Acts as a conductive salt in electrodeposition processes for metals and alloys.

Quality Control

Our Trihexyl(Tetradecyl)Phosphonium Bis(Trifluoromethylsulfonyl)Imide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing exact specifications for purity, water content, and halide impurities are available upon request.

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) and should be handled under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong acids and strong oxidizing agents.
