1-Methyl-3-nonylimidazolium tetrafluoroborate, CAS: 244193-55-3

Key Applications:

• Electrochemical Systems
  • Hydrophobic ionic liquid electrolyte for supercapacitors, advanced batteries, and high‑voltage electrochemical devices.

• • Wide electrochemical stability window and low volatility support long‑term cycling performance.
• Organic Synthesis & Catalysis

• • Polar, non‑coordinating solvent for transition‑metal catalysis, nucleophilic substitutions, and biphasic reaction systems.
  • Supports phase‑transfer catalysis and simplifies product isolation due to immiscibility with water.
• Thermal & Process Fluids

• • High thermal stability and negligible vapor pressure make it suitable for heat‑transfer media, thermostatting baths, and high‑temperature reaction environments.
• Self‑Assembly, Micelles & Soft‑Matter Systems

• • Long nonyl chain imparts amphiphilicity, enabling formation of micelles, lyotropic liquid crystalline phases, and nanostructured soft‑matter templates.
  • Useful in interfacial chemistry and surfactant‑like behavior studies.
• Lubrication & Tribology

• • Functions as a boundary lubricant and anti‑wear additive for metals and alloys.
  • BF₄⁻ salts exhibit low corrosivity and stable film formation under load.
• Extraction & Separation

• • Effective in liquid–liquid extraction of aromatics, polar organics, and selected metal ions.
  • Hydrophobicity reduces solvent loss and enhances selectivity.
• Nanomaterials & Surface Modification

• • Serves as a templating agent, stabilizer, or dispersant in nanoparticle synthesis and carbon‑based materials.
  • Enhances dispersion in hydrophobic polymer matrices.
