1-Hexyl-3-methylimidazolium hexafluorophosphate, CAS: 304680-35-1

Key Applications:

• Lithium Metal Batteries

HMIM PF₆ serves as a high‑stability ionic medium that supports advanced lithium metal battery research.

• • Acting as a non‑volatile, electrochemically stable component in electrolyte formulations.
  • Improving interfacial stability at the lithium metal surface due to the imidazolium cation’s ability to form structured interphases.
  • Enhancing ionic conductivity when blended with lithium salts, especially in systems requiring hydrophobic, low‑water‑content environments.
  • Supporting high‑temperature cycling studies, where PF₆⁻‑based ionic liquids maintain structural integrity.
• Extraction Solvents

HMIM PF₆ is widely used as a hydrophobic ionic liquid phase in liquid–liquid extraction systems.

• • Selective extraction of transition metals, lanthanides, and actinides, leveraging strong ion‑pairing with PF₆⁻.
  • Separation of aromatic hydrocarbons, phenolic compounds, and organic acids due to tunable polarity and negligible vapor pressure.
  • Serving as a green alternative to volatile organic solvents in biphasic extraction processes.
  • Enabling back‑extraction and phase regeneration because of its chemical robustness and low miscibility with water.
• Dispersive Liquid–Liquid Microextraction (DLLME)

HMIM PF₆ functions effectively as an ionic liquid extractant in DLLME workflows.

• • Rapid formation of a fine dispersion when combined with a disperser solvent, increasing analyte transfer efficiency.
  • High affinity for hydrophobic and moderately polar analytes, improving enrichment factors.
  • Compatibility with HPLC, GC, and spectroscopic detection due to low volatility and easy phase separation.
  • Reduced solvent consumption, aligning with green analytical chemistry principles.
