1,3-Diethylimidazolium tetrafluoroborate, CAS: 847335-65-3

Key Applications:

Electrochemical Systems

• Serves as a stable ionic liquid electrolyte component for supercapacitors and advanced battery chemistries.
• Supports wide electrochemical windows, enabling high‑voltage device development.
• Used in electrodeposition studies for metals and semiconductors due to its low volatility and ionic conductivity.

Catalysis & Organic Synthesis

• Functions as a non‑volatile reaction medium for acid‑catalyzed and transition‑metal‑catalyzed transformations.
• Applied in biphasic catalytic systems where phase separation and recyclability are required.
• Enhances selectivity and yield in nucleophilic substitution, alkylation, and cyclization reactions.

Separation Science & Extraction

• Utilized in liquid–liquid extraction of metal ions, aromatic compounds, and biomass‑derived molecules.
• Supports tunable solvation environments for selective separation processes.
• Employed in supported ionic liquid membranes (SILMs) for gas separation and purification.

Materials Science & Nanotechnology

• Acts as a templating or stabilizing medium for nanoparticle synthesis, including metals and metal oxides.
• Used in polymer electrolyte formulations to improve ionic transport and mechanical stability.
• Serves as a processing aid in the fabrication of ionic‑liquid‑based gels and composite materials.

Thermal & Green Chemistry Applications

• Provides a thermally stable, low‑vapor‑pressure alternative to conventional organic solvents.
• Supports sustainable reaction engineering by enabling solvent recycling and reduced emissions.
• Applied in high‑temperature processes where conventional solvents degrade or volatilize.
